Excited states in the Thomas–Fermi limit: a variational approach
Excited state condensate semi-classical Thomas Fermi extreme exclusion
2014/12/24
Excited states of Bose–Einstein condensates are considered in the semi-classical (Thomas- Fermi) limit of the Gross–Pitaevskii equation with repulsive inter-atomic interactions and a harmonic potentia...
Distribution of eigenfrequencies for oscillations of the ground state in the Thomas-Fermi limit
Systematic distribution ground vibration bose-einstein condensate 3 d
2014/12/24
In this work, we present a systematic derivation of the distribution of eigenfrequencies for oscillations of the ground state of a repulsive Bose-Einstein condensate in the semi-classical (Thomas-Ferm...
Thomas-Fermi approximation to pairing in finite Fermi systems. The weak coupling regime
Thomas-Fermi approximation to pairing Fermi systems weak coupling regime
2011/7/20
We present a new semiclassical theory for describing pairing in finite Fermi systems. It is based on taking the $\hbar \to 0$, i.e. Thomas-Fermi, limit of the gap equation written in the basis of the ...
