Quantum criticality of a one-dimensional Bose-Fermi mixture
Xiangguo Yin, Xi-Wen Guan, Yunbo Zhang +1
The one-dimensional interacting Bose-Fermi mixtures, exhibiting quantum phase transitions at zero temperature, are particularly valuable for the study of quantum critical phenomena…
One-dimensional multicomponent fermions with delta function interaction in strong and weak coupling limits: Two-component Fermi gas
Xi-Wen Guan, Zhong-Qi Ma
The Fredholm equations for one-dimensional two-component Fermions with repulsive and with attractive delta-function interactions are solved by an asymptotic expansion for A) strong…
Thermodynamics and spin-charge separation of one-dimensional strongly repulsive three-component fermions
Peng He, Jen Yee Lee, Xiwen Guan +2
The low temperature thermodynamics of one-dimensional strongly repulsive SU(3) fermions in the presence of a magnetic field is investigated via the Yang-Yang thermodynamic Bethe an…
Quantum criticality and universal scaling of strongly attractive spin-imbalanced Fermi gases in a 1D harmonic trap
Xiangguo Yin, Xi-Wen Guan, Shu Chen +1
We investigate thermodynamics and quantum criticality of strongly attractive Fermi gases confined in a one-dimensional (1D) harmonic trap. Finite temperature density profiles, entr…
