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…
Critical exponents of the disorder-driven superfluid-insulator transition in one-dimensional Bose-Einstein condensates
J. C. C. Cestari, A. Foerster, M. A. Gusmão +1
We investigate the nature of the superfluid-insulator quantum phase transition driven by disorder for non-interacting ultracold atoms on one-dimensional lattices. We consider two 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…
Thermal and magnetic properties of integrable spin-1 and spin-3/2 chains with applications to real compounds
M. T. Batchelor, X. -W. Guan, N. Oelkers +1
The ground state and thermodynamic properties of spin-1 and spin-3/2 chains are investigated via exactly solved su(3) and su(4) models with physically motivated chemical potential…
