Thermodynamic properties of a long-range interacting Bose system in staggered magnetic field

摘要

This paper provides a brief introduction to the thermodynamic properties of long-range interaction Bose systems in the staggered magnetic field by using the microcanonical approach. The entropy, temperature, heat capacity, phase translation are analyzed separately, and we constructed global phase diagram of the system. First-order phase transition, second-order phase transition, and negative specific heat can be observed in such system.
