Bose-Einstein Condensates in Time Dependent Traps
Yvan Castin, Ralph Dum
We present analytical results for the macroscopic wave function of a Bose-Einstein condensate in a time dependent harmonic potential. The evolution of the spatial density is a dila…
Fourth cluster and virial coefficients of a unitary Fermi gas for an arbitrary mass ratio
Shimpei Endo, Yvan Castin
We calculate the fourth cluster coefficients of the homogeneous unitary spin 1/2 Fermi gas as functions of the internal-state mass ratio, over intervals constrained by the 3- or 4-…
Nuclear spin squeezing by continuous quantum non-demolition measurement: a theoretical study
Alan Serafin, Yvan Castin, Matteo Fadel +2
We propose to take advantage of the weak coupling of ground-state helium-3 nuclear spin to its environment to produce long-lived macroscopic quantum states, nuclear spin squeezed s…
Random walk of a massive quasiparticle in the phonon gas of an ultralow temperature superfluid
Yvan Castin
We consider a 3D homogeneous superfluid at low temperature with 2 types of excitations, gapless phonons with a linear dispersion relation at low wavenumber, and gapped quasipar…
Bragg spectroscopy and pair-breaking-continuum mode in a superfluid Fermi gas
Yvan Castin
The superfluid, pair condensed spin-1/2 Fermi gases are supposed to exhibit at nonzero wave vector a still unobserved collective excitation mode in their pair-breaking continuum. U…
Collective excitation branch in the continuum of pair-condensed Fermi gases : analytical study and scaling laws
Yvan Castin, Hadrien Kurkjian
The pair-condensed unpolarized spin- Fermi gases have a collective excitation branch in their pair-breaking continuum (V.A. Andrianov, V.N. Popov, 1976). We study it at zero t…
