Lee-Yang zeros and two-time spin correlation function
Kh. P. Gnatenko, A. Kargol, V. M. Tkachuk
The two-time correlation function for probe spin interacting with spin system (bath) is studied. We show that zeros of this function correspond to zeros of partition function of sp…
Time correlation functions and Fisher zeros for q-deformed Bose gas
Kh. P. Gnatenko, A. Kargol, V. M. Tkachuk
The time-dependent correlation functions of q-deformed Bose gas are studied. We find relation of zeros of the correlation functions with the Fisher zeros of partition function of t…
Two-time correlation functions and the Lee-Yang zeros for an interacting Bose gas
Kh. P. Gnatenko, A. Kargol, V. M. Tkachuk
Two-time correlation functions of a system of Bose particles are studied. We find relation of zeros of the correlation functions with the Lee-Yang zeros of partition function of th…
