Universal Drude Weights in One-dimensional Repulsive Fermi Gas
Xiangguo Yin, Dawei Niu, Shuang Zhang +3
Building on the Bethe ansatz and generalized hydrodynamics, we rigorously establish universal relations between Drude weights governing charge, spin, and energy transport and therm…
Universal Transport Properties of Continuous Quantum Gases
Zi-yang Liu, Xiangguo Yin, Yunbo Zhang +2
The Drude weight characterizes ballistic transport in quantum many-body systems. Although analytical calculations of Drude weights have been extensively studied in integrable model…
Critical behaviours of contact near phase transitions
Y. -Y. Chen, Y. -Z. Jiang, X. -W. Guan +1
A central quantity of importance for ultracold atoms is contact, which measures two-body correlations at short distances in dilute systems. It appears in universal relations among…
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…

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…
Universal Tomonaga-Luttinger liquid phases in one-dimensional strongly attractive SU(N) fermionic cold atoms
