Chiral Effects in Quantum Rotor Systems

Russian Physics Journal Aims and scope

The statistical mechanics and thermodynamics of a system of symmetric rigid quantum rotors in the field of centrifugal forces are considered. Using the theory of canonical ensembles, we find one-particle distribution function, and the partition function and thermodynamic potential are expressed as a function of temperature and angular velocity. The equation of state in the angular velocity–angular momentum–temperature coordinates is explicitly found in the high-temperature and ultra-cold cases. The macroscopic parameters of the system show a dependence on the angular velocity, so the chiral effects are present in the system. The magnitude of chiral effects is estimated. The entropy and angular momentum graphs are plotted in the ultra-cold case.
