Ground state energy of the two-dimensional weakly interacting Bose gas: First correction beyond Bogoliubov theory
Christophe Mora, Yvan Castin
We consider the grand potential of a two-dimensional weakly interacting homogeneous Bose gas at zero temperature. Building on a number-conserving Bogoliubov method for a lattic…
Superfluidity of the 1D Bose gas
Iacopo Carusotto, Yvan Castin
We have investigated the superfluid properties of a ring of weakly interacting and degenerate 1D Bose gas at thermal equilibrium with a rotating vessel. The conventional definition…
Limits of sympathetic cooling of fermions: The role of the heat capacity of the coolant
L. D. Carr, Y. Castin
The sympathetic cooling of an initially degenerate Fermi gas by either an ideal Bose gas below or an ideal Boltzmann gas is investigated. It is shown that the efficiency of c…
Vortex crystallisation in classical field theory
Carlos Lobo, Alice Sinatra, Yvan Castin
We show that the formation of a vortex lattice in a weakly interacting Bose condensed gas can be modeled with the nonlinear Schrodinger equation for both T=0 and finite temperature…
Extension of Bogoliubov theory to quasi-condensates
Christophe Mora, Yvan Castin
We present an extension of the well-known Bogoliubov theory to treat low dimensional degenerate Bose gases in the limit of weak interactions and low density fluctuations. We use a…
