Finite Temperature Properties of Three-Component Fermion Systems in Optical Lattice

TL;DR

This paper studies the finite temperature behavior of three-component fermion systems in optical lattices, revealing the stability of color density-wave states, reentrant phase transitions, and the maximum critical temperature for symmetry-breaking phases.

Contribution

It provides new insights into the thermal stability and phase transitions of multicomponent fermionic systems, highlighting the dominance of color density-wave states and reentrant behavior.

Findings

Color density-wave state is more stable than CSAF at finite temperature.

Reentrant phase boundary behavior observed for CSAF state.

Maximum critical temperature for symmetry-breaking states identified.

Abstract

We investigate finite temperature properties in the half-filled three-component (colors) fermion systems. It is clarified that a color density-wave (CDW) state is more stable than a color-selective "antiferromagnetic" (CSAF) state against thermal fluctuations. The reentrant behavior in the phase boundary for the CSAF state is found. We also address the maximum critical temperature of the translational symmetry breaking states in the multicomponent fermionic systems.
