New asymptotic behaviour of the surface-atom force out of thermal equilibrium
Mauro Antezza, Lev P. Pitaevskii, Sandro Stringari
The Casimir-Polder-Lifshitz force felt by an atom near the surface of a substrate is calculated out of thermal equilibrium in terms of the dielectric function of the material and o…
Effect of the Casimir-Polder force on the collective oscillations of a trapped Bose-Einstein condensate
Mauro Antezza, Lev P. Pitaevskii, Sandro Stringari
We calculate the effect of the interaction between an optically active material and a Bose-Einstein condensate on the collective oscillations of the condensate. We provide explicit…
Bose-Einstein condensates in 1D optical lattices: compressibility, Bloch bands and elementary excitations
Meret Kraemer, Chiara Menotti, Lev Pitaevskii +1
We discuss the Bloch-state solutions of the stationary Gross-Pitaevskii equation and of the Bogoliubov equations for a Bose-Einstein condensate in the presence of a one-dimensional…
Finite size effects on the collective oscillations of a trapped Bose gas
Francesca Zambelli, Sandro Stringari
Sum rules are used to calculate the corrections to the hydrodynamic collective frequencies of a harmonically trapped Bose gas at T=0, due to finite size effects. We show that, with…
Vortex nucleation and quadrupole deformation of a rotating Bose-Einstein condensate
M. Kraemer, L. Pitaevskii, S. Stringari +1
Using a semi-analytic model based on the Thomas-Fermi approximation, we investigate the relevance of the quadrupole deformation of a trapped Bose-Einstein condensate for the nuclea…
Time dependent density functional theory in quantum liquids
Sandro Stringari
The formalism of density functional theory (DFT) can be easily extended to the time dependent case (TDDFT). However, while in the static case the theory is well established and is…
