Energy-dependent effective interactions for dilute many-body systems
A. Collin, P. Massignan, C. J. Pethick
We address the issue of determining an effective two-body interaction for mean-field calculations of energies of many-body systems. We show that the effective interaction is propor…

Three-dimensional strong localization of matter waves by scattering from atoms in a lattice with a confinement-induced resonance
Pietro Massignan, Yvan Castin
The possibility of using ultracold atoms to observe strong localization of matter waves is now the subject of a great interest, as undesirable decoherence and interactions can be m…

Viscous relaxation and collective oscillations in a trapped Fermi gas near the unitarity limit
P. Massignan, G. M. Bruun, H. Smith
The viscous relaxation time of a trapped two-component gas of fermions in its normal phase is calculated as a function of temperature and scattering length, with the collision prob…
