Long-range interacting spin-1 chains: phase diagram and thermodynamic properties
首发时间:2017-04-28
Abstract:The long-range interacting spin-1 chain placed in a staggered magnetic field is studied by means of microcanonical approach. Firstly, we study the microcanonical entropy of the system and find the system is nonergodic and can exhibit either first order phase transition or second order phase transition by shifting the external magnetic field strength. Secondly, we construct the the global phase diagram of the system and find a phase transition area in the phase diagram corresponding to the temperature jump of the first order phase transition.
