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…
Kinematic variables in noncommutative phase space and parameters of noncommutativity
Kh. P. Gnatenko
We consider a space with noncommutativity of coordinates and noncommutativity of momenta. It is shown that coordinates in noncommutative phase space depend on mass therefore they c…
Noncommutative phase space with rotational symmetry and hydrogen atom
Kh. P. Gnatenko, V. M. Tkachuk
We construct algebra with noncommutativity of coordinates and noncommutativity of momenta which is rotationally invariant and equivalent to noncommutative algebra of canonical type…
Two-particle system in noncommutative space with preserved rotational symmetry
Kh. P. Gnatenko, V. M. Tkachuk
We consider a system of two particles in noncommutative space which is rotationally invariant. It is shown that the coordinates of the center-of-mass position and the coordinates o…
