Asymptotic formula condensate wave function trapped Bose gas
2015/10/16
An analytical property is pointed out for the universal differential equation first derived by Dalfovo, Pitaevskii, and Stringari for the condensate wave function at the boundary of a trapped Bose gas...
FLUCTUATIONS OF THE BOSE-EINSTEIN CONDENSATE。
The two-dimensional Bose-Einstein condensate
Trapped bose gas low temperature condensation thermodynamics
2014/12/20
We study the Hartree–Fock–Bogoliubov mean-field theory as applied to a two-dimensional finite trapped Bose gas at low temperatures and find that, in the Hartree–Fock approximation, the system can be d...
Superfluid-Superfluid Phase Transitions in a Two-Component Bose-Einstein Condensate
Hamiltonian parameters bosons optical lattice superfluid superfluids vacuum
2014/12/20
Depending on the Hamiltonian parameters, two-component bosons in an optical lattice can form at least three different superfluid phases in which both components participate in the superflow: a (strong...
Scaling laws for the non-linear coupling constant of a Bose-Einstein condensate at the threshold of delocalization
Scaling laws the non-linear coupling constant Bose-Einstein condensate threshold of delocalization
2012/2/28
We explore the localization of a quasi-one-, quasi-two-, and three-dimensional ultra-cold gas by a finite-range defect along the corresponding 'free'-direction/s. The time-independent non-linear Schro...

2011/9/15
In a recent experiment, a Bose-Einstein condensate of 7Li has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an analytical perturbati...

2011/10/14
The eigen mode of spin oscillations with $\omega\simeq \sqrt{58/35}\Delta$ is predicted to exist besides already known spin waves with $\omega \simeq\Delta /\sqrt{5}$ in the triplet superfluid neutron...
Viscous Hydrodynamic Evolution with Non-Boost Invariant Flow for the Color Glass Condensate
Viscous Hydrodynamic Color Glass Condensate
2011/7/20
The Large Hadron Collider (LHC) experiments have revealed that the predictions of the color glass condensate (CGC) tend to underestimate the multiplicity at mid-rapidity.

Bose-Einstein condensate gases of rare atomic species Atomic Physics
2011/8/1
Abstract: We report on the successful extension of production of Bose-Einstein Condensate (BEC) to rare species. Despite its low natural abundance of 0.13%, $^{168}$Yb is directly evaporatively cooled...
I present recent analytical work concerning the electric-magnetic asymmetry in the dimension two condensate in pure Yang-Mills theory. We reproduce qualitatively the lattice results previously f...
Analytic approach to the study of the electric-magnetic asymmetry of the dimension 2 condensate

2010/12/23
Recent work by Chernodub and Ilgenfritz has uncovered non-trivial temperature dependence in the electric-magnetic asymmetry in the dimension 2 condensate. This asymmetry measures the difference betwe...
Many physicists believed it could not be done, but now a team in Germany has created a Bose–Einstein condensate (BEC) from photons. BECs are formed when identical bosons – particles with integer spin ...
