Role of energy uncertainties in ergodicity breaking induced by competing interactions and disorder. A dynamical assessment through the Loschmidt echo
Pablo R. Zangara, Patricia R. Levstein, Horacio M. Pastawski
A local excitation in a quantum many-particle system evolves deterministically. A time-reversal procedure, involving the invertion of the signs of every energy and interaction, sho…
Time Fluctuations in Isolated Quantum Systems of Interacting Particles
Pablo R. Zangara, Axel D. Dente, E. J. Torres-Herrera +3
Numerically, we study the time fluctuations of few-body observables after relaxation in isolated dynamical quantum systems of interacting particles. Our results suggest that they d…
Interaction-disorder competition in a spin system evaluated through the Loschmidt Echo
Pablo R. Zangara, Axel D. Dente, Aníbal Iucci +2
The interplay between interactions and disorder in closed quantum many-body systems is relevant for thermalization phenomenon. In this article, we address this competition in an in…
