We show that, within mean-field theory, the density profile of a rapidly rotating harmonically trapped Bose-Einstein condensate is of the Thomas-Fermi form... Gentaro,Watanabe,Gordon,... - 《Physical Review Letters》 被引量: 137发表: 2004年 An $n$n-dimensional interpretation of the $delta$...
Surprisingly, we find\nthat the usual Gaussian profile assumption for the strongly confining direction\nis inappropriate for the cigar-shaped BEC case, and a Thomas-Fermi type profile\nshould be adopted instead. Based on the derived mean field equations, the\nThomas-Fermi densities are analyzed ...
Firstly, we show that the ground state has the limit behaviors as N → + ∞ No+\infty , which corresponds to a Thomas-Fermi limit. The limit profile is given by the Thomas-Fermi minimizer u T F ( x ) = [ μ T F C 0 | x | p ] 1 4 + u^{TF}(x)=\left[\mu^{TF}-C...
A recently introduced analytical model for the nuclear density profile[1] is implemented in the Extended Thomas-Fermi (ETF) energy density functional. This allows to (i) shed a new light on the issue of the sign of surface symmetry energy in nuclear mass formulas, which is strongly related ...

We applied this method to three n-type direct-gap III–V model semiconductors (GaAs, InAs, InSb) and found that the Thomas–Fermi approximation is certainly valid at high electron densities. In these cases, the probability density function exhibits the same pro...
Thomas-FermiMethodElectronSpectrumElectron spectrum in doped n-Si quantum wires is calculated by the Thomas-Fermi (TF) method under finite temperatures. The many-body exchange corrections are taken into account. The doping profile is arbitrary. At the first stage, the electron potential energy is ...
