The mathematical model of th is mechanism is based on the hydrodynamic equations of active matter and t akes into account the dynamics of the environment polarization and polariz ation of individual bacteria. It is assumed that the flow of light and the active motion of dielectric regions with different refractive indices ins ide the bacterium lead to the formation of a nonuniform distribution of di pole moments at the interface between the bacterium and the aqueous medium . This distribution is nonequilibrium and evolves along the bacterium and rotates. The interaction of this distribution with the environment due to surface deformation or due to ponderomotive force leads to the bacteria's motion. Such a motion can be represented as a type of turbine effect witho ut attachment or as an interaction of the polarization current with a chan ge in the local polarization of the medium. This mechanism differs signifi cantly from the flagella motion mechanism and can explain the motility of flagellate bacteria. In addition\, such a mechanism depends on the concent ration of charged particles in the medium. Namely\, with an increase in th eir concentration\, the polarized region motion increases\, which creates a greater bacterial surface deformation and causes a redistribution of pol arization. Moreover\, the collective bacteria motion can cause water mixin g.\n\nhttps://indico.bitp.kiev.ua/event/13/contributions/328/ LOCATION:Bogolyubov Institute for Theoretical Physics (Section 1-4)\, Inst itute of Mathematics (Section 5) 322 URL:https://indico.bitp.kiev.ua/event/13/contributions/328/ END:VEVENT BEGIN:VEVENT SUMMARY:Kinetic model of the formation of STM-induced electrofluorochromis m in molecular junctions DTSTART;VALUE=DATE-TIME:20240926T095000Z DTEND;VALUE=DATE-TIME:20240926T101000Z DTSTAMP;VALUE=DATE-TIME:20260723T012339Z UID:indico-contribution-75-333@indico.bitp.kiev.ua DESCRIPTION:Speakers: Oleksiy Kapitanchuk (Bogolyubov Institute for Theore tical Physics\, National Academy of Sciences of Ukraine)\nExperimental dat a on STM-induced electroluminescence in monomolecular junctions have led t o the need to elucidate the physics of the formation of optoelectronic pro cesses at the atomic-molecular level\, taking into account both dynamic an d relaxation processes. A mechanism for the formation of electrofluorochro mism based on a kinetic model has been proposed [1]. In this model\, the d escription of the optoelectronic process in a photoactive molecular juncti on takes into account the fact that the formation of electron current and electroluminescence (EL) is controlled not only by the shift of the orbita l energies of the molecule relative to the Fermi levels of both electrodes \, but also by the probability of the realization of many-body states of t he molecule at different values and polarities of the bias voltage. Theref ore\, when current and EL are generated\, the electronic states of charged forms of fluorophore molecules can act not only as mediators of electron transfer\, but also become responsible for electrofluorochromism. It becam e clear that the EL in a molecular junction reflects the light emission of a fluorophore molecule not only between the singlet states of a neutral m olecule\, but also between the states of its charged forms. Thus\, we show that electron transfer occurs through the transmission channels associate d with electronic states of the neutral molecule and its cationic and anio nic forms\, which\, at a definite bias voltages\, are involved in electron transfer. The occupancies of these states are determined by kinetic proce sses in the molecular junction and therefore depend on the ratio of charg e exchange rates between the molecule and the electrodes\, the rates of no n-radiative intramolecular transitions caused by inelastic interelectrode tunneling of electrons\, as well as the rates of intramolecular radiative transitions enhanced by the plasmonic response. Analytical results are obt ained using the tight-binding Hamiltonian for a molecule. The kinetic mode l made it possible to explain the features of EL in a monomolecular juncti on with the ZnPc fluorophore. Thus\, it was shown that the description of EL based on the kinetic approach can serve as an effective tool for unders tanding the physics of optoelectronic processes in single-molecule structu res.\n\n1.

The fundamental equations of modern mathematical phy sics are studied\, in particular the hierarchies of the evolution equation s of many hard spheres and their asymptotic behavior described by kinetic nonlinear equations.\n\nFirst\, an approach to describing correlations in a system of colliding particles interacting as hard spheres is discussed\, based on a hierarchy of equations for the evolution of a sequence of corr elation functions that are cumulants of distribution functions\, called th e Lioville hierarchy. It is proven that the constructed dynamics of correl ations underlie the description of the dynamics of both a finite and an in finite number of hard spheres obeying the BBGKY hierarchies for reduced (m arginal) distribution functions or reduced correlation functions.\n\nThe s tructure of expansions representing non-perturbative solutions of the Cauc hy problem for these hierarchies of evolution equations is formulated. It has been established that the concept of cumulants of the groups of operat ors of the Lioville equations underlies non-perturbative expansions of sol utions to the hierarchies of fundamental equations describing the evolutio n of observables and of the state of many hard spheres\, as well as forms the basis of the kinetic description of their collective behavior.\n\nIn t he talk\, we also consider a new approach to the problem of a rigorous des cription of kinetic evolution by means of reduced (marginal) observables g overned by the dual BBGKY hierarchy. One of the advantages of the develope d approach to the derivation of kinetic equations from the underlying dyna mics of many particles is that it provides an opportunity to construct kin etic equations with initial correlations\, in particular correlations char acterizing the condensed states of a system\, and to describe the processe s of the propagation of initial correlations within suitable scaling limit s.\n\nReferences\n[1] Gerasimenko V I and Gapyak I V 2023 Advances in theo ry of evolution equations of many colliding particles. *Proc.

Vakhnenko (Bogolyubov Institute for Theor etical Physics)\nFollowing the main principles of developing the evolution ary nonlinear integrable systems on quasi-one-dimensional lattices we sugg est the novel nonlinear integrable system of parametrically driven pseudo- excitations on a regular two-leg ladder lattice. The initial (prototype) f orm of the system is derivable in the framework of semi-discrete zero-curv ature equation with the spectral and evolution operators specified by the properly organized 3×3 square matrices. Although the lowest conserved loc al densities found via the direct recursive method do not prompt us the al gebraic structure of system's Hamiltonian function\, but the heuristically substantiated search for the suitable two-stage transformation of prototy pe field functions to the physically motivated ones has allowed to disclos e the physically meaningful nonlinear integrable system with time-dependen t longitudinal and transverse inter-site coupling parameters. The time dep endencies of inter-site coupling parameters in the transformed system are consistently dened in terms of the accompanying parametric driver formaliz ed by the set of four homogeneous ordinary linear dierential equations wit h the time-dependent coeficients. The physically meaningful parametrically driven nonlinear system permits its concise Hamiltonian formulation with the two pairs of field functions serving as the two pairs of canonically c onjugated field amplitudes. The explicit example of oscillatory parametric drive is described in full mathematical details.\n\nhttps://indico.bitp.k iev.ua/event/13/contributions/336/ LOCATION:Bogolyubov Institute for Theoretical Physics (Section 1-4)\, Inst itute of Mathematics (Section 5) 322 URL:https://indico.bitp.kiev.ua/event/13/contributions/336/ END:VEVENT BEGIN:VEVENT SUMMARY:Stimulating exitable membrane of ORN with stochastic Markov proces s DTSTART;VALUE=DATE-TIME:20240926T082000Z DTEND;VALUE=DATE-TIME:20240926T084000Z DTSTAMP;VALUE=DATE-TIME:20260723T012339Z UID:indico-contribution-75-358@indico.bitp.kiev.ua DESCRIPTION:Speakers: Oleksandr Vidybida (Bogolyubov Institute for Theoret ical Physics)\nExcitable membrane of olfactory receptor neuron (ORN) is po pulated with up to several millions of identical receptor proteins (R) abl e to bind / release odor (O) molecules. The affinity of R to O depends on the odor presented\, and this is the initial mechanism which is recuired f or the olfactory selectivity to exist.\n\n\nFigure 1: Simplified R structu re. Modified from [3].\n\nThe affinity of R to O depends on the odor prese nted\, and this is the very first step the olfactory selectivity builds up . Recently\, [1]\, it was shown for a so called membrane-less ORN model th at its selectivity can be much better than that of its R. A more realistic ORN model should include an excitable membrane with its electric transien ts. This introduces time parameter into the ORN's response to stimulation. The latter renders inappropriate used in [1] reasoning in terms of binomi al distribution\, and necessitates consideration of temporal properties of O binding-releasing and the membrane charging-discharging-firing.\n\nIn t his contribution\, we develop an approach in which the number of R bound w ith O $n(t)$\, is modeled as a Markov stochastic process. With each bound R\, \nas it is observed for insects [2]\, Fig. 1\, we associate an open ch annel having conductance 0.015 nS\, which injects a depolarizing current t hrough the membrane.\n The futher membrane evolution is governed by the le aky integrate-and-fire neuronal model\, see Eq. (1).\n$c_M\\frac{dV(t)}{dt }=-g_l(V(t)-V_{rest}) - n(t)g_{R}(V(t)-V_{e})$\,\nwhere $V(t)$ --- is the membrane voltage\; $V_{rest}$ --- is the resting voltage\;\n$c_M$ --- is t he total capacity of ORN's membrane\;\n$g_l$ --- is the total leakage thro ugh it\;\n$V_{e}$ --- is the reversal potential for current through open $ R$\;\n$n(t)$ --- is the fluctuating number of open channels at moment $t$ due\nto odor molecules bound with $R$s\;\n$g_{R}$ --- is the conductance o f a single open channel.\n\nA fast\, very efficient method is developed fo r generating stochastic trajectories $n(t)$ and solving Eq. (1) numericall y\, see Fig. 2. The first\, introductory simulations based on this method\ , [4]\, support the conclusion made in [1] and before\, that ORN's selecti vity can be much better than that of its receptors R\, provided that odors are presented in low concentrations.\n\n\nFigure 2: An example of realiza tion of stochastic process n(t) and corresponding membrane voltage\, with three spikes emitted.

V. Kurdyumov Institute for Metal Physics\, N.A.S. of Ukraine)\nThe generalized recursive method for calcul ating the T-matrix of electron scattering on arbitrary many-particle clust ers for determining the Green's function of the strongly correlated system is developed. This approach is extended to the studying electronic spectr a in both direct (Wannier) and reciprocal (Bloch) representations with tak ing into account the influence of atomic and magnetic correlations arising in the system at a temperature of 0 K. The one-band Hubbard model\, the c orrelated random field approximation\, and the one-site coherent potential approximation for the effective Hamiltonian of system are also used in th is approach. The spectral density in reciprocal space is calculated in the same way (the same scheme) as in direct space\, using the appropriate exp ressions for the effective Green's function\, which includes contributions from all crystal sublattices. Calculation of the small parameter of the c luster expansion of the Green's function in direct and reciprocal represen tations shows its smallness for different parameters of b.c.c alloys. This ensures the convergence of obtained recursive formulas for T-matrix of sc attering on many-particle clusters and the applicability of pairwise appro ximation for T-matrix. It should be noted that to calculate the configurat ion-averaged Green's function it is necessary to use at least the pairwise approximation of T-matrix for describing the influence of the cluster env ironment of each atom on the redistribution of charge and spin densities o n atoms\, as well as atomic and magnetic correlations. In addition\, the p ossibility of nanoclusters formation and their influence on the magnetic s tate was investigated in the b.c.c. alloy with strong electron correlation s. The calculation of electronic spectra in the reciprocal (as in direct) representation showed the high sensitivity to the changes in the character istics and composition of the b.c.c. alloy including the nanoclusters form ation as well as to the change of resulting short-range atomic and magneti c orders.

The validity of LGD approach is corroborated by experimental evi dence of the size- and strain-induced transitions as well as the related p henomena in the low-dimensional ferroelectric materials. For the correct d escription of these effects in ferroelectric thin films and small nanopart icles the LGD approach should be combined with the classical electrostatic s and elasticity theory\, and variational principle. It is important to de termine how the LGD expansion coefficients depend on various factors\, suc h as temperature\, size\, elastic stresses and/or strains\, and ionic-elec tronic charge density and distribution. For classical ferroelectric films with a pronounced temperature-dependent and strain-dependent soft mode\, t he first expansion coefficients have a linear dependence on the temperatur e and elastic strain.\nThe significant attention is devoted to the compari son with experimental results and finite element modelling\, as well as on the theoretical predictions of the size-\, strain- and ionic- control of polar and dielectric properties of nanosized ferroelectric materials.\nAs the first example\, we consider ultra-thin layers and nanoflakes of van de r Waals ferrielectric CuInP2S6 covered by an ionic surface charge and reve al the appearance of polar states with relatively high polarization and st ored free charge\, which can mimic “mid-gap” states related with a sur face field-induced transfer of Cu and/or In ions in the van der Waals gap [1]. The changes of the ionic screening degree and mismatch strains can in duce the transitions between paraelectric phase\, antiferroelectric\, ferr ielectric\, and ferroelectric-like states in CuInP2S6 nanoflakes. Due to t he emergence of manyfold-degenerated metastable states of spontaneous pola rization the ultra-thin layers of CuInP2S6 reveal features of the controll able negative capacitance effect [2]\, which make them attractive for adva nced electronic devices\, such as nano-capacitors and gate oxide nanomater ials with reduced heat dissipation.\nAs the second example\, we use the LG D model to quantify the strain-charge-polarization coupling in nanosized H fxZr1-xO2. A key factor ruling the observed polar properties of nanosized HfxZr1-xO2 is the presence of the polar orthorhombic phase. This phase is metastabile compared to the bulk monoclinic phase\, leading to problems wi th the ferroelectric phase stability in nanoscale. The electrophysical pro perties of the HfxZr1-xO2 thin films and nanoparticles are very sensitive to the elastic strain induced by the substrate\, annealing conditions\, de position method\, film thickness\, content x and dopants. Depending on the interplay of these factors\, the nanosized HfxZr1-xO2 exhibits dielectric \, ferroelectric\, or antiferroelectric behavior. \nThe used model [3] inc orporates parametrized Landau expansion coefficients for the polar and ant ipolar orderings. Obtained results agrees with the recent existing experim ental data for HfxZr1-xO2-y thin films and oxygen-deficient HfO2-y nanopar ticles [4]\, namely the X-ray diffraction confirmed the formation of a fer roelectric orthorhombic phase in the HfO2-y nanoparticles under special fa vorable annealing conditions. \nThe analytical LGD approach correctly pred icts the phase diagrams\, ground and metastable states\, alongside the dom ain structure morphology\, associated polar and structural properties of H fxZr1-xO2-y thin films and nanoparticles with different shapes and sizes. The successful application of the analytical LGD approach can be useful fo r the prediction of the silicon-compatible ferroelectric nanomaterials bas ed on HfxZr1-xO2-y. \nThe work is funded by the National Research Foundati on of Ukraine (projects “Manyfold-degenerated metastable states of spont aneous polarization in nanoferroics: theory\, experiment and perspectives for digital nanoelectronics”\, grant N 2023.03/0132 and “Silicon-compa tible ferroelectric nanocomposites for electronics and sensors”\, grant N 2023.03/0127).\n[1].
