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…
Quantum phase transitions in Bose-Einstein condensates from a Bethe ansatz perspective
D. Rubeni, A. Foerster, E. Mattei +1
We investigate two solvable models for Bose-Einstein condensates and extract physical information by studying the structure of the solutions of their Bethe ansatz equations. A care…
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…
