Fermionic Meixner probability distributions, Lie algebras and quadratic Hamiltonians
L. Accardi, I. Ya. Aref'eva, I. V. Volovich
We introduce the quadratic Fermi algebra, which is a Lie algebra, and show that the vacuum distributions of the associated Hamiltonians define the fermionic Meixner probability dis…
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…
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)…
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-Equilibrium Quantum Field Theory and Entangled Commutation Relations
L. Accardi, I. Ya. Aref'eva, I. V. Volovich
Non-equilibrium quantum field theory studies time dependence of processes which are not available for the S-matrix description. One of the new methods of investigation in non-equil…
