Many experimentally relevant systems are quasi-one-dimensional, consisting of nearly decoupled chains. In these systems, there is a natural separation of scales between the strong intra-chain interactions and the weak interchain coupling. When the intra-chain interactions are integrable, weak interchain couplings play a crucial part in thermalizing the system. Here, we develop a Boltzmann-equation formalism involving a collision integral that is asymptotically exact for any interacting…

Integrable quantum systems of finite size are generically robust against weak enough integrabilitybreaking perturbations, but become quantum chaotic and thermalizing if the integrability-breaking is
