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…
Universal local pair correlations of Lieb-Liniger bosons at quantum criticality
M. -S. Wang, J. -H. Huang, C. -H. Lee +3
The one-dimensional Lieb-Liniger Bose gas is a prototypical many-body system featuring universal Tomonaga-Luttinger liquid (TLL) physics and free fermion quantum criticality. We an…
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…
