Wilson ratio of Fermi gases in one dimension
X. W. Guan, X. G. Yin, A. Foerster +3
We calculate the Wilson ratio of the one-dimensional Fermi gas with spin imbalance. The Wilson ratio of attractively interacting fermions is solely determined by the density stiffn…
Universality class of quantum criticality for strongly repulsive spin-1 bosons with antiferromagnetic spin-exchange interaction
C. C. N. Kuhn, X. W. Guan, A. Foerster +1
Using the thermodynamic Bethe ansatz equations we study the quantum phase diagram, thermodynamics and criticality of one-dimensional spin-1 bosons with strongly repulsive density-d…
Quantum criticality of spin-1 bosons in a 1D harmonic trap
C. C. N. Kuhn, X. W. Guan, A. Foerster +1
We investigate universal thermodynamics and quantum criticality of spin-1 bosons with strongly repulsive density-density and antiferromagnetic spin-exchange interactions in a one-d…
Thermodynamics, spin-charge separation and correlation functions of spin-1/2 fermions with repulsive interaction
J. Y. Lee, X. W. Guan, K. Sakai +1
We investigate the low temperature thermodynamics and correlation functions of one-dimensional spin-1/2 fermions with strong repulsion in an external magnetic field via the thermod…
Exactly solvable models and ultracold Fermi gases
Murray T. Batchelor, Angela Foerster, Xiwen Guan +1
Exactly solvable models of ultracold Fermi gases are reviewed via their thermodynamic Bethe Ansatz solution. Analytical and numerical results are obtained for the thermodynamics an…
Effective super Tonks-Girardeau gases as ground states of strongly attractive multi-component fermions
Xiangguo Yin, Xi-Wen Guan, M T Batchelor +1
In the strong interaction limit, attractive fermions with -component hyperfine states in a one-dimensional waveguide form unbreakable bound cluster states. We demonstrate that t…
