Description

Eigenstate thermalization hypothesis is a cornerstone of our modern understanding of thermalization and relaxation phenomena in quantum many-body systems. The studies mainly focus on chaotic dynamics, where there is solid numerical evidence supporting the standard ETH. The are however conflicting statements regarding its validity in integrable systems. By motivating and introducing a refined version of the ETH ansatz, I will discuss the structure and statistical properties of off-diagonal matrix elements in a simple integrable quantum field theory.
