Ergodicity, eigenstate thermalization, and the foundations of statistical mechanics in quantum and classical systems
Lorenzo Campos Venuti, Lawrence Liu
Boltzmann's ergodic hypothesis furnishes a possible explanation for the emergence of statistical mechanics in the framework of classical physics. In quantum mechanics, the Eigensta…
Equilibration times in clean and noisy systems
Lorenzo Campos Venuti, Sunil Yeshwanth, Stephan Haas
We study the equilibration dynamics of closed finite quantum systems and address the question of the time needed for the system to equilibrate. In particular we focus on the scalin…
Gaussian Equilibration
Lorenzo Campos Venuti, Paolo Zanardi
A finite quantum system evolving unitarily equilibrates in a probabilistic fashion. In the general many-body setting the time-fluctuations of an observable \mathcal{A} are typicall…
Rapidly-converging methods for the location of quantum critical points from finite-size data
M. Roncaglia, L. Campos Venuti, C. Degli Esposti Boschi
We analyze in detail, beyond the usual scaling hypothesis, the finite-size convergence of static quantities toward the thermodynamic limit. In this way we are able to obtain sequen…
The fidelity approach to the Hubbard model
L. Campos Venuti, M. Cozzini, P. Buonsante +3
We use the fidelity approach to quantum critical points to study the zero temperature phase diagram of the one-dimensional Hubbard model. Using a variety of analytical and numerica…
