DESCRIPTION:Speakers: Yurii Zhuravlov (Bogolyubov Institute for Theoretica
 l Physics of the National Academy of Sciences of Ukraine)\nWe study therma
 l correlation functions of the one-dimensional impenetrable lattice anyons
 . These correlation functions can be presented as a difference of two Fred
 holm determinants. To describe large time and long distance behavior of th
 ese objects we use effective form factor approach. The asymptotic behavior
  is different in the space-like and time-like regions. In particular\, in 
 the time-like region we observe the additional power factor on top of the 
 exponential decay. We argue that this result is universal as it is related
  to the discontinuous behavior of the phase shift function of the effectiv
 e fermions. At particular values of the anyonic parameter we recover asymp
 totics of spin-spin correlation functions in XXO quantum chain.\n\nhttps:/
