Probing quantum statistical mechanics with Bose gases: Non-trivial order parameter topology from a Bose-Einstein quench
نویسندگان
چکیده
A rapid second order phase transition can have a significant probability of producing a metastable state instead of the equilibrium state. We consider the case of rapid BoseEinstein condensation in a toroidal trap resulting in a spontaneous superfluid current, and compare the phenomenological time-dependent Ginzburg-Landau theory with quantum kinetic theory. A simple model suggests the effect should be observable.

Stochastic Optimization of Bose-Einstein Condensation Using a Genetic Algorithm
In 1924/25, Satyendranath Bose and Albert Einstein predicted that particles of integer spin (today called bosons) should undergo a quantum statistical phase transition when cooled to temperatures very close to absolute zero (Bose, 1924; Einstein, 1925). This phenomenon, nowadays called Bose-Einstein condensation, has been experimentally observed seventy years later using ultracold (nanokelvin t...

The modified Gross-Pitaevskii equation was derived and solved to obtain the 1D solution in the zero-energy limit. This stationary solution could account for the dominated contributions due to the kinetic effect as well as the chemical potential in inhomogeneous Bose gases. Studies of collision phenomena in rather cold gases, e.g., dilute Bose gases, have recently attracted many researchers' att...
متن کاملBose-Einstein-condensed gases with arbitrary strong interactions
Bose-condensed gases are considered with an effective interaction strength varying in the whole range of the values between zero and infinity. The consideration is based on the usage of a representative statistical ensemble for Bose systems with broken global gauge symmetry. Practical calculations are illustrated for a uniform Bose gas at zero temperature, employing a self-consistent mean-field...
متن کاملDynamics and thermodynamics in spinor quantum gases
We discuss magnetism in spinor quantum gases theoretically and experimentally with emphasis on temporal dynamics of the spinor order parameter in the presence of an external agnetic field. In a simple coupled Gross-Pitaevskii picture we observe a dramatic suppression of spin dynamics due to quadratic Zeeman ”dephasing”. In view of an inhomogeneous density profile of the trapped condensate we pr...
متن کاملThe Gross-Pitaevskii Equation and Bose-Einstein condensates
The Gross-Pitaevskii equation is discussed at the level of an advanced course on statistical physics. In the standard literature the Gross-Pitaevskii equation is usually obtained in the framework of the second quantisation formalism, which in many cases goes beyond the material covered in many advanced undergraduate courses. In this paper, we motivate the derivation of the Gross-Pitaevskii equa...
