Momentum dependent quantum Ruelle-Pollicott resonances in
translationally invariant many-body systems
We study Ruelle-Pollicott resonances in translationally invariant quantum many-body systems via spectra of momentum-resolved operator propagator on infinite systems. Momentum dependence gives insight into decay of correlation functions, showing that, depending on their symmetries, different correlation functions in general decay with different rates. Focusing on the kicked Ising model the …
