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…
Superfluidity in the stochastic limit
L. Accardi, S. V. Kozyrev
In the present paper we outline the stochastic limit approach to superfluidity. The Hamiltonian describing the interaction between the Bose condensate and the normal phase is intro…
The stochastic limit of quantum spin systems
L. Accardi, S. V. Kozyrev
The stochastic limit for the system of spins interacting with a boson field is investigated. In the finite volume an application of the stochastic golden rule shows that in the lim…
Non-Exponential Decay for Polaron Model
L. Accardi, S. V. Kozyrev, I. V. Volovich
A model of particle interacting with quantum field is considered. The model includes as particular cases the polaron model and non-relativistic quantum electrodynamics. We compute…
Dynamics of Dissipative Two-Level Systems in the Stochastic Approximation
L. Accardi, S. V. Kozyrev, I. V. Volovich
The dynamics of the spin-boson Hamiltonian is considered in the stochastic approximation. The Hamiltonian describes a two-level system coupled to an environment and is widely used…
