Quantum phase transition in a spin-1/2 XX chain with three-spin and uniform long-range interactions
Source PublicationPHYSICA STATUS SOLIDI B-BASIC SOLID STATE PHYSICS
AbstractA spin-1/2 XX chain with three-spin and uniform long-range interactions among the z components of the spins is constructed. Based upon the model, using the Jordan-Wigner transformation, the thermodynamic quantities and spin transports of the system are evaluated exactly. The phase diagram together with the key parameters characterizing quantum phase transitions is presented. It is noted that, similarly to classical first-order phase transitions, there are also the metastable states "supercooled" and "superheated" in the first-order quantum phase transitions.
