Integrability as a consequence of discrete holomorphicity: loop models
I T Alam, M T Batchelor
In this paper, we explore the relationship between integrability and the discrete holomorphicity of a class of complex lattice observables in the context of the Potts dense loop mo…
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…
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…
Integrability as a consequence of discrete holomorphicity: the Z_N model
I. T. Alam, M. T. Batchelor
It has recently been established that imposing the condition of discrete holomorphicity on a lattice parafermionic observable leads to the critical Boltzmann weights in a number of…
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…
