Supercurrent stability in a quasi-one-dimensional weakly interacting Bose gas
Superfluid phenomena bose gas liquid and super current
2014/12/22
We discuss the possibility of observing superfluid phenomena in a quasi-one-dimensional weakly interacting Bose gas at finite temperature. The weakness of interaction in combination with generic prope...
Critical Temperature Shift in Weakly Interacting Bose Gas
High performance monte carlo quantum bose gas the scattering
2014/12/22
With a high-performance Monte Carlo algorithm we study the interaction-induced shift of the critical point in weakly interacting three-dimensional |ψ|4 theory (which includes quantum Bose gas). In ter...
Two-dimensional weakly interacting Bose gas in the fluctuation region
Two-dimensional bose gas range cross thermodynamics parameters superfluids
2014/12/22
We study the crossover between the mean-field and critical behavior of the two-dimensional Bose gas throughout the fluctuation region of the Berezinskii-Kosterlitz-Thouless phase transition point. We ...
Weakly Interacting Bose Gas in the Vicinity of the Critical Point
Three dimensional weak bose gas the thermodynamic functions superfluid density
2014/12/20
We consider a three-dimensional weakly interacting Bose gas in the fluctuation region (and its vicinity) of the normal-superfluid phase transition point. We establish relations between basic thermodyn...
The Beliaev technique for a weakly interacting Bose gas
Control precision thermodynamics correlation function interaction bose gas the symmetry
2014/12/18
Aiming at simplicity of explicit equations and, at the same time, controllable accuracy of the theory, we present our results for all the thermodynamic quantities and correlation functions for a weakl...
