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…
Out of Time Order Correlations in the Quasi-Periodic Aubry-André model
Jonathon Riddell, Erik S. Sørensen
We study out of time ordered correlators (OTOC) in a free fermionic model with a quasi-periodic potential. This model is equivalent to the Aubry-André model and features a phase tr…
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…
Out of Time Ordered Correlators and Entanglement Growth in the Random Field XX Spin Chain
Jonathon Riddell, Erik S. Sorensen
We study out of time order correlations, and entanglement growth in the random field XX model with open boundary conditions using the exact Jordan-Wigner transformation to…
Generalized eigenstate typicality in translation-invariant quasifree fermionic models
Jonathon Riddell, Markus P. Mueller
We demonstrate a generalized notion of eigenstate thermalization for translation-invariant quasifree fermionic models: the vast majority of eigenstates satisfying a finite number o…
