Relaxation of non-integrable systems and correlation functions
Jonathon Riddell, Luis Pedro García-Pintos, Álvaro M. Alhambra
We investigate early-time equilibration rates of observables in closed many-body quantum systems and compare them to those of two correlation functions, first introduced by Kubo an…

Time evolution of correlation functions in quantum many-body systems
Álvaro M. Alhambra, Jonathon Riddell, Luis Pedro García-Pintos
We give rigorous analytical results on the temporal behavior of two-point correlation functions --also known as dynamical response functions or Green's functions-- in closed many-b…
