Atomic spin sensitive dissipation on magnetic surfaces
Franco Pellegrini, Giuseppe E. Santoro, Erio Tosatti
We identify the mechanism of energy dissipation relevant to spin-sensitive nanomechanics including the recently introduced magnetic exchange force microscopy, where oscillating mag…
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…
