Power-law decay of correlations after a global quench in the massive XXZ chain
Flávia B. Ramos, Andrew Urichuk, Imke Schneider +1
We investigate the relaxation dynamics of equal-time correlations in the antiferromagnetic phase of the XXZ spin-1/2 chain following a global quantum quench of the anisotropy param…
Symmetry-Resolved Entanglement of -symmetric Topological Insulators
K. Monkman, J. Sirker
For a many-body system of arbitrary dimension, we consider fermionic ground states of non-interacting Hamiltonians invariant under a cyclic group. The absolute difference …
Entanglement and particle fluctuations of one-dimensional chiral topological insulators
K. Monkman, J. Sirker
We consider the topological protection of entanglement and particle fluctuations for a general one-dimensional chiral topological insulator with winding number . We pr…
Non-linear Transport by Bethe Bound States
A. Urichuk, A. Klümper, J. Sirker
We consider non-linear ballistic spin transport in the XXZ spin chain and derive an analytical result for the non-linear Drude weight at infinite temperatures. In contras…
Spin and charge order in doped spin-orbit coupled Mott insulators
Mehdi Biderang, Alireza Akbari, Jesko Sirker
We study a two-dimensional single band Hubbard Hamiltonian with antisymmetric spin-orbit coupling. We argue that this is the minimal model to understand the electronic properties o…
Transport in one-dimensional integrable quantum systems
J. Sirker
These notes are based on a series of three lectures given at the Les Houches summer school on 'Integrability in Atomic and Condensed Matter Physics' in August 2018. They provide an…
