Quantum criticality of a one-dimensional Bose-Fermi mixture

Yin, Xiangguo; Guan, Xi-Wen; Zhang, Yunbo; Chen, Shu

Description

The one-dimensional interacting Bose-Fermi mixtures, exhibiting quantum phase transitions at zero temperature, are particularly valuable for the study of quantum critical phenomena. In the present paper, we analytically study the quantum phase diagram, equation of state, and quantum criticality of the Bose-Fermi mixture using the thermodynamic Bethe ansatz equations. We show that thermodynamical properties display universal scaling behavior at quantum criticality. Furthermore, quantum...[Show more]
