Microscopic Computational Model of a Superfluid (2009)

Ovchinnikov, Mikhail, Novikov, Alexey

A finite one-dimensional microscopic model of a superfulid is presented. The model consists of interacting Bose particles with an additional impurity particle confined to a ring. Both semiclassical...

Diagrammatic calculation of energy spectrum of quantum impurity in degenerate Bose-Einstein condensate (2008)

Novikov, Alexey, Ovchinnikov, Mikhail

In this paper we considered a quantum particle moving through delute Bose-Einstein condensate at zero temperature. In our formulation the impurity particle interacts with the gas of uncoupled...

Motion of quantum particle in dilute Bose-Einstein condensate at zero temperature (2008)

Novikov, Alexey, Ovchinnikov, Mikhail

The motion of single quantum particle through Bose-Einstein condensate (BEC) is considered within perturbation theory with respect to the particle-BEC interaction. The Hamiltonian of BEC is...

Path integral formulation of dissipative quantum dynamics (2005)

Novikov, Alexey

In this thesis the path integral formalism is applied to the calculation of the dynamics of dissipative quantum systems. The time evolution of a system of bilinearly coupled bosonic modes is treated...

Simple Method for Repurification of Endotoxins for Biological Use▿

Tirsoaga, Alina, Novikov, Alexey, Adib-Conquy, Minou, Werts, Catherine, Fitting, Catherine, Cavaillon, Jean-Marc, ...

A method for obtaining highly purified endotoxin (lipopolysaccharide [LPS]) in a few hours by repurification of commercial or laboratory preparations was devised. It avoids the use of phenol, which...
