Quantum Arnol'd Diffusion in a Simple Nonlinear System
V. Ya. Demikhovskii, F. M. Izrailev, A. I. Malyshev
We study the fingerprint of the Arnol'd diffusion in a quantum system of two coupled nonlinear oscillators with a two-frequency external force. In the classical description, this p…
Delocalization border and onset of chaos in a model of quantum computation
G. P. Berman, F. Borgonovi, F. M. Izrailev +1
We study the properties of spectra and eigenfunctions for a chain of spins (qubits) in an external time-dependent magnetic field, and under the conditions of non-selective e…
Entropy production and wave packet dynamics in the Fock space of closed chaotic many-body systems
V. V. Flambaum, F. M. Izrailev
Highly excited many-particle states in quantum systems such as nuclei, atoms, quantum dots, spin systems, quantum computers etc., can be considered as ``chaotic'' superpositions of…
Unconventional decay law for excited states in closed many-body systems
V. V. Flambaum, F. M. Izrailev
We study the time evolution of an initially excited many-body state in a finite system of interacting Fermi-particles in the situation when the interaction gives rise to the ``chao…
Avoiding Quantum Chaos in Quantum Computation
G. P. Berman, F. Borgonovi, F. M. Izrailev +1
We study a one-dimensional chain of nuclear spins in an external time-dependent magnetic field. This model is considered as a possible candidate for experimental realization…
