Relaxation due to random collisions with a many-qudit environment

Giuseppe Gennaro, Giuliano Benenti, G. Massimo Palma

We analyze the dynamics of a system qudit of dimension mu sequentially interacting with the nu-dimensional qudits of a chain playing the ore of an environment. Each pairwise collis…

Spinor Dynamics of Quantum Accelerator Modes near Higher Order Resonances

L. Rebuzzini, I. Guarneri, R. Artuso

Quantum Accelerator Modes were discovered in experiments with Kicked Cold Atoms in the presence of gravity. They were shown to be tightly related to resonances of the Quantum Kicke…

Semiclassical model for a memory dephasing channel

A. D'Arrigo, G. Benenti, G. Falci

We study a dephasing channel with memory, described by a Hamiltonian model in which the system-environment interaction is described by a stochastic process. We propose a useful way…

Gaussian wave packets in phase space: The Fermi g_F function

Giuliano Benenti, Giuliano Strini

Any pure quantum state can be equivalently represented by means of its wave function psi(q) or of the Fermi function g_F(q,p), with q and p coordinates and conjugate momenta of the…

Optimal purification of a generic n-qudit state

Giuliano Benenti, Giuliano Strini

We propose a quantum algorithm for the purification of a generic mixed state of a -qudit system by using an ancillary -qudit system. The algorithm is optimal in that (i)…

Quantum Semi-Markov Processes

Heinz-Peter Breuer, Bassano Vacchini

We construct a large class of non-Markovian master equations that describe the dynamics of open quantum systems featuring strong memory effects, which relies on a quantum generaliz…

Kinetic description of quantum Brownian motion

Bassano Vacchini, Francesco Petruccione

We stress the relevance of the two features of translational invariance and atomic nature of the gas in the quantum description of the motion of a massive test particle in a gas, c…

How complex is the quantum motion?

Giuliano Benenti, Giulio Casati

In classical mechanics the complexity of a dynamical system is characterized by the rate of local exponential instability which effaces the memory of initial conditions and leads t…

Non-Markovian dynamics for bipartite systems

Bassano Vacchini

We analyze the appearance of non-Markovian effects in the dynamics of a bipartite system coupled to a reservoir, which can be described within a class of non-Markovian equations gi…

Efficient positronium laser excitation for antihydrogen production in a magnetic field

F. Castelli, I. Boscolo, S. Cialdi +2

Antihydrogen production by charge exchange reaction between Positronium (Ps) atoms and antiprotons requires an efficient excitation of Ps atoms up to high-n levels (Rydberg levels)…

Feedback control of the fluorescence light squeezing

A. Barchielli, M. Gregoratti, M. Licciardo

We consider a two-level atom stimulated by a coherent monochromatic laser and we study how to enhance the squeezing of the fluorescence light and of the atom itself in the presence…

Properties of entangled photon pairs generated by a CW laser with small coherence time: theory and experiment

Simone Cialdi, Fabrizio Castelli, Matteo G. A. Paris

The generation of entangled photon pairs by parametric down--conversion from solid state CW lasers with small coherence time is theoretically and experimentally analyzed. We consid…

Entanglement-induced Decoherence and Energy Eigenstates

Wen-ge Wang, Jiangbin Gong, G. Casati +1

Using recent results in the field of quantum chaos we derive explicit expressions for the time scale of decoherence induced by the system-environment entanglement. For a generic sy…

Entanglement dynamics and relaxation in a few qubit system interacting with random collisions

Giuseppe Gennaro, Giuliano Benenti, Massimo Palma

The dynamics of a single qubit interacting by a sequence of pairwise collisions with an environment consisting of just two more qubits is analyzed. Each collision is modeled in ter…
