Adiabatic quenches through an extended quantum critical region
Franco Pellegrini, Simone Montangero, Giuseppe E. Santoro +1
By gradually changing the degree of the anisotropy in a XXZ chain we study the defect formation in a quantum system that crosses an extended critical region. We discuss two qualita…

Fractal Fidelity as a signature of Quantum Chaos
Franco Pellegrini, Simone Montangero
We analyze the fidelity of a quantum simulation and we show that it displays fractal fluctuations iff the simulated dynamics is chaotic. This analysis allows us to investigate a gi…
