Weak integrability breaking perturbations of integrable models
A quantum integrable system slightly perturbed away from integrability is typically expected to thermalize on timescales of order τ∼λ^{−2}, where λ is the perturbation strength. We here study classes of perturbations that violate this scaling, and exhibit much longer thermalization times τ∼λ^{−2ℓ} w...
