Atom-atom correlations in colliding Bose-Einstein condensates
Magnus Ogren, K. V. Kheruntsyan
We analyze atom-atom correlations in the s-wave scattering halo of two colliding condensates. By developing a simple perturbative approach, we obtain explicit analytic results for…

Superfluidity in a gas of strongly-interacting bosons
G. M. Kavoulakis, Y. Yu, M. Ogren +1
We consider small systems of bosonic atoms rotating in a toroidal trap. Using the method of exact numerical diagonalization of the many-body Hamiltonian, we examine the transition…

Supershell structure in trapped dilute Fermi gases
Y. Yu, M. Ogren, S. Aberg +2
We show that a dilute harmonically trapped two-component gas of fermionic atoms with a weak repulsive interaction has a pronounced super-shell structure: the shell fillings due to…
