We study the impact of the photon subsystem on the magnetic properties of a mixture of quantum gases in thermodynamic equilibrium with it. Having proposed a simple model of the system, we obtain general equations describing the thermodynamic equilibrium of quantum gases of two-level atoms with photons. The resulting equations are solved at a temperature higher than the degeneracy temperature...
The search of a target of unknown location is often random and ineffective, especially when the search domain is spacious and there is a lot of detrimental trajectories. To get rid of them, thereby improving the search, interruptions of the latter with starting it from scratch can be a good strategy. Called resetting, such a manner is in fact inherent to many search processes at very diverse...
A rapid growth of Machine Learning (ML) applications in different areas has been faced in recent years. Training of ML models is performed by finding such values of their parameters $x=\{x_1, x_2, ..., x_N\}$ that optimize (minimize) the objective (loss) function $U(x)$. Usually, the number of parameters $N$ is large and the training dataset is massive. Therefore, to reduce computational...
Within the framework of the mean-field model, the thermodynamics of the relativistic bosonic system of interacting particles and antiparticles in the presence of a Bose-Einstein condensate is investigated. It is assumed that the total isospin (charge) density is conserved. It is shown that the particle-antiparticle boson system reveals four types of phase transitions into the condensate phase....
The chemical freeze-out curve in heavy-ion collisions is investigated in the context of QCD critical point (CP) search at finite baryon densities. Taking the hadron resonance gas picture at face value, chemical freeze-out points at a given baryochemical potential provide a lower bound on the possible temperature of the QCD CP. We first verify that the freeze-out data in heavy-ion collisions...
