Quantum Poincare Recurrences for Hydrogen Atom in a Microwave Field
Giuliano Benenti, Giulio Casati, Giulio Maspero +1
We study the time dependence of the ionization probability of Rydberg atoms driven by a microwave field, both in classical and in quantum mechanics. The quantum survival probabilit…
Quantum Poincaré Recurrences
Giulio Casati, Giulio Maspero, Dima L. Shepelyansky
We show that quantum effects modify the decay rate of Poincaré recurrences P(t) in classical chaotic systems with hierarchical structure of phase space. The exponent p of the algeb…
Quantum Fractal Eigenstates
Giulio Casati, Giulio Maspero, Dima L. Shepelyansky
We study quantum chaos in open dynamical systems and show that it is characterized by quantum fractal eigenstates located on the underlying classical strange repeller. The states w…
Relaxation process in a regime of quantum chaos
Giulio Casati, Giulio Maspero, Dima L. Shepelyansky
We show that the quantum relaxation process in a classically chaotic open dynamical system is characterized by a quantum relaxation time scale t_q. This scale is much shorter than…
Landauer and Thouless Conductance: a Band Random Matrix Approach
Giulio Casati, Italo Guarneri, Giulio Maspero
We numerically analyze the transmission through a thin disordered wire of finite length attached to perfect leads, by making use of banded random Hamiltonian matrices. We compare t…
