We investigate a classical phase-space approach of matter-wave propagation based on the truncated Wigner equation (TWE). We show that such a description is suitable for ideal matter waves in quadratic time-dependent confinement as well as for harmonically trapped Bose-Einstein condensates in the Thomas-Fermi regime. In arbitrary interacting regimes, the TWE combined with the moment method yields the low-energy spectrum of a condensate as predicted by independent variational methods. TWE also… Expand
Mean-field Wigner function of Bose–Einstein condensates in the Thomas–Fermi limit
We study the mean-field phase-space distribution of the ground state of an anisotropic, harmonically trapped Bose–Einstein condensate at zero temperature. First, we derive the Fourier transform ofExpand

Wigner function of noninteracting trapped fermions
We study analytically the Wigner function W N (x,p) of N noninteracting fermions trapped in a smooth confining potential V (x) in d dimensions. At zero temperature, W N (x,p) is constant over aExpand
Free evolution of an incoherent mixture of states: a quantum mechanical approach to the van Cittert–Zernike theorem

Low Energy Excitations of a Bose-Einstein Condensate: A Time-Dependent Variational Analysis.
The time-dependent Gross-Pitaevskii equation is solved by a variational ansatz to calculate the excitation spectrum of a Bose-Einstein condensate in a trap and results reproduce numerical calculations over the whole range from small to large particle numbers, and agree exactly with the Stringari results in the strong interaction limit.

Analytical results for the macroscopic wave function of a Bose-Einstein condensate in a time dependent harmonic potential are presented, characterized by three scaling factors which allow a classical interpretation of the dynamics. Expand
