Dynamical localization simulated on a few qubits quantum computer
Giuliano Benenti, Giulio Casati, Simone Montangero +1
We show that a quantum computer operating with a small number of qubits can simulate the dynamical localization of classical chaos in a system described by the quantum sawtooth map…
On the stability of classical chaotic motion under system's perturbations
Giuliano Benenti, Giulio Casati, Gregor Veble
We study in detail the time behavior of classical fidelity for chaotic systems. We show in particular that the asymptotic decay, depending on system dynamical properties, can be ei…
Transition to an Insulating Phase Induced by Attractive Interactions in the Disordered Three-Dimensional Hubbard Model
Bhargavi Srinivasan, Giuliano Benenti, Dima L. Shepelyansky
We study numerically the interplay of disorder and attractive interactions for spin-1/2 fermions in the three-dimensional Hubbard model. The results obtained by projector quantum M…
