Quantum master equations for a system interacting with quantum gas in the low density limit and for the semiclassical collision model
S. N. Filippov, G. N. Semin, A. N. Pechen
A quantum system interacting with a dilute gas experiences irreversible dynamics. The corresponding master equation can be derived within two different approaches: The fully quantu…
White noise approach to the low density limit of a quantum particle in a gas
Alexander Pechen
The white noise approach to the investigation of the dynamics of a quantum particle interacting with a dilute and in general non-equilibrium gaseous environment in the low density…
Coherent quantum control of -atoms through the stochastic limit
L. Accardi, S. V. Kozyrev, A. N. Pechen
We investigate, using the stochastic limit method, the coherent quantum control of a 3-level atom in -configuration interacting with two laser fields. We prove that, in the gene…
Quantum stochastic equation for test particle interacting with dilute Bose gas
A. N. Pechen
We use the stochastic limit method to study long time quantum dynamics of a test particle interacting with a dilute Bose gas. The case of arbitrary form-factors and an arbitrary, n…
A stochastic golden rule and quantum Langevin equation for the low density limit
L. Accardi, A. N. Pechen, I. V. Volovich
A rigorous derivation of quantum Langevin equation from microscopic dynamics in the low density limit is given. We consider a quantum model of a microscopic system (test particle)…
Space Dependence of Entangled States and Franson-type EPR Experiments
A. A. Baranov, A. N. Pechen, I. V. Volovich
We analyze some aspects of recently performed Franson-type experiments with entangled photon pairs aimed to test Bell's inequalities. We point out that quantum theory leads to the…
