Weak integrability breaking perturbations in classical integrable models on the lattice
Sara Vanovac, Catherine McCarthy, Federica Maria Surace +1
We show how to systematically construct weak integrability breaking perturbations (WIBs) for classical integrable models on the lattice. These perturbations, which allow quasi-cons…

Finite-size generators for weak integrability breaking perturbations in the Heisenberg chain
Sara Vanovac, Federica Maria Surace, Olexei Motrunich
An integrable model perturbed by special ''weak integrability-breaking'' perturbations thermalizes at timescales much longer than predicted by Fermi's golden rule. Recently, a syst…
