... where U (ri ) is the trapping potential and V (ri , rj ) is the interaction potential. If the fermions are non-interacting (i.e. V = 0), then a simple exact solution for the properties of the gas exists for any temperature of the gas. Quantum statistical mechanics, in the Thomas-Fermi approximation ...

Equation (11.4) predicts an apparent enhancement, at nonzero temperature, of the fluctuationinduced interaction, relative to the Casimir-Polder limit.. This does not necessarily happen, however, because the molecular polarizabilities are al ...

A controlled quantum system of individual neutral atoms
... The heart of our apparatus is an optical dipole trap which confines atoms in the antinodes of a far off-resonance standing wave. This type of trap relies on the dipole force, arising from inhomogeneous light fields. The first proposal of using this force to trap atoms was made by V. Letokhov already ...

Moving to higher frequencies is advantageous since a number of systematic corrections do not scale with frequency at all, so there is an immediate improv ...

Although several implementations exist, the principle of evaporative cooling is always the same: one removes atoms carrying a large energy from the trap, so as to decrease the mean energy - hence the temperature - of the remaining particles. This is achieved by truncating ...
