On computing non-equilibrium dynamics following a quench
Neil J. Robinson, Albertus J. J. M. de Klerk, Jean-Sébastien Caux
Computing the non-equilibrium dynamics that follows a quantum quench is difficult, even in exactly solvable models. Results are often predicated on the ability to compute overlaps…
Characterizing the quantum field theory vacuum using temporal Matrix Product states
Emanuele Tirrito, Neil J. Robinson, Maciej Lewenstein +2
In this paper we construct the continuous Matrix Product State (MPS) representation of the vacuum of the field theory corresponding to the continuous limit of an Ising model. We do…
Nonthermal states arising from confinement in one and two dimensions
Andrew J. A. James, Robert M. Konik, Neil J. Robinson
We show that confinement in the quantum Ising model leads to nonthermal eigenstates, in both continuum and lattice theories, in both one (1D) and two dimensions (2D). In the ordere…
Thermalization and light cones in a model with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We employ equation of motion techniques to study the non-equilibrium dynamics in a lattice model of weakly interacting spinless fermions. Our model provides a simple setting for an…
Prethermalization and thermalization in models with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We study the effects of integrability breaking perturbations on the non-equilibrium evolution of many-particle quantum systems. We focus on a class of spinless fermion models with…
Quench Dynamics in a Model with Tuneable Integrability Breaking
F. H. L. Essler, S. Kehrein, S. R. Manmana +1
We consider quantum quenches in an integrable quantum chain with tuneable-integrability-breaking interactions. In the case where these interactions are weak, we demonstrate that at…
