The discovery of Bose–Einstein condensation (BEC) in trapped ultracold atomic gases in
1995 has led to an explosion of theoretical and experimental research on the properties of …

The theoretical description of trapped weakly interacting Bose–Einstein condensates is
characterized by a large number of seemingly very different approaches which have been …

We study experimentally the transverse monopole mode of an elongated rubidium
condensate. Because of the scaling invariance of the nonlinear Schrödinger (Gross …

We present a variational solution of the Langevin field equation describing the
nonequilibrium dynamics of a harmonically trapped Bose-Einstein condensate. If the thermal …

We consider a model of a dilute Bose-Einstein condensed gas at finite temperatures, where
the condensate coexists in a trap with a cloud of thermal excitations. Within the Zaremba …

Finite-temperature simulations are used to study quadrupole excitations of a trapped Bose-
Einstein condensate. We focus specifically on the m= 0 mode, where a long-standing …

We study the breathing (monopole) oscillations and their dam** in a harmonically trapped
onedimensional (1D) Bose gas in the quasicondensate regime using a finite-temperature …

We present numerical results from a second-order quantum field theory of Bose-Einstein
condensates applied to the 1997 JILA experiment [DS ** et al., Phys. Rev. Lett. 78, 764 …

We describe a number-conserving approach to the dynamics of Bose-Einstein condensed
dilute atomic gases. This builds upon the works of Gardiner [Phys. Rev. A 56, 1414 (1997)] …

We present a convenient technique describing the condensate in dynamical equilibrium with
the thermal cloud, at temperatures close to the critical one. We show that the whole isolated …
