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…
Internal structure of a quantum soliton and classical excitations due to trap opening
Yvan Castin
We analytically solve two problems that may be useful in the context of the recent observation of matter wave bright solitons in a one-dimensional attractive atomic Bose gas. The f…
Number of closed-channel molecules in the BEC-BCS crossover
Felix Werner, Leticia Tarruell, Yvan Castin
Using a two-channel model, we show that the number of closed channel molecules in a two-component Fermi gas close to a Feshbach resonance is directly related to the derivative of t…
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…
