Genuine phase diffusion of a Bose-Einstein condensate in the microcanonical ensemble: A classical field study
Alice Sinatra, Yvan Castin
Within the classical field model, we find that the phase of a Bose-Einstein condensate undergoes a true diffusive motion in the microcanonical ensemble, the variance of the condens…
Creation and detection of a mesoscopic gas in a non-local quantum superposition
Christoph Weiss, Yvan Castin
We investigate the scattering of a quantum matter wave soliton on a barrier in a one dimensional geometry and we show that it can lead to mesoscopic Schrödinger cat states, where t…
Three fully polarized fermions close to a p-wave Feshbach resonance
Mattia Jona-Lasinio, Ludovic Pricoupenko, Yvan Castin
We study the three-body problem for three atomic fermions, in the same spin state, experiencing a resonant interaction in the p-wave channel via a Feshbach resonance represented by…
A semi-classical field method for the equilibrium Bose gas and application to thermal vortices in two dimensions
Luca Giorgetti, Iacopo Carusotto, Yvan Castin
We develop a semi-classical field method for the study of the weakly interacting Bose gas at finite temperature, which, contrarily to the usual classical field model, does not suff…
Three fermions in a box at the unitary limit: universality in a lattice model
Ludovic Pricoupenko, Yvan Castin
We consider three fermions with two spin components interacting on a lattice model with an infinite scattering length. Low lying eigenenergies in a cubic box with periodic boundary…
Basic theory tools for degenerate Fermi gases
Yvan Castin
This is an introductory lecture to the theory of degenerate Fermi gases, in the context of present experiments on atomic Fermi gases. In part one, some properties of the ideal Ferm…
