Quasi-local charges and the Generalized Gibbs Ensemble in the Lieb-Liniger model
Tamas Palmai, Robert M. Konik
We consider the construction of a generalized Gibbs ensemble composed of complete bases of conserved charges in the repulsive Lieb-Liniger model. We will show that it is possible t…
Probing non-thermal density fluctuations in the one-dimensional Bose gas
Jacopo De Nardis, Miłosz Panfil, Andrea Gambassi +3
Quantum integrable models display a rich variety of non-thermal excited states with unusual properties. The most common way to probe them is by performing a quantum quench, i.e., b…
Large-scale description of interacting one-dimensional Bose gases: generalized hydrodynamics supersedes conventional hydrodynamics
Benjamin Doyon, Jérôme Dubail, Robert Konik +1
The theory of generalized hydrodynamics (GHD) was recently developed as a new tool for the study of inhomogeneous time evolution in many-body interacting systems with infinitely ma…
Non-perturbative methodologies for low-dimensional strongly-correlated systems: From non-abelian bosonization to truncated spectrum methods
Andrew J. A. James, Robert M. Konik, Philippe Lecheminant +2
We review two important non-perturbative approaches for extracting the physics of low-dimensional strongly correlated quantum systems. Firstly, we start by providing a comprehensiv…
Excitations in the Yang-Gaudin Bose gas
Neil J. Robinson, Robert M. Konik
We study the excitation spectrum of two-component delta-function interacting bosons confined to a single spatial dimension, the Yang-Gaudin Bose gas. We show that there are pronoun…
