Measuring the Lyapunov exponent using quantum mechanics
F. M. Cucchietti, C. H. Lewenkopf, E. R. Mucciolo +2
We study the time evolution of two wave packets prepared at the same initial state, but evolving under slightly different Hamiltonians. For chaotic systems, we determine the circum…

Sensitivity to perturbations in a quantum chaotic billiard
Diego A. Wisniacki, Eduardo Vergini, Horacio M. Pastawski +1
The Loschmidt echo (LE) measures the ability of a system to return to the initial state after a forward quantum evolution followed by a backward perturbed one. It has been conjectu…
