We investigate the effects of a trapping space-dependent potential on the low-temperature quasilong-range order phase of two-dimensional particle systems with a relevant U(1) symmetry, such as quantum...

Integrability breakdown one-dimensional bosonic gases
2010/11/17
A system of identical bosons with short-range (contact) interactions is studied. Their motion is confined to one dimension by a tight lateral trapping potential and, additionally, subject to a weak ha...
We present a lattice study of up to N = 20 unitary fermions confined to a harmonic trap. Our
preliminary results show better than 1% agreement with high precision solutions to the many-body Schroding...

Motion of dark solitons trapped Bose-Einstein condensates

We use a multiple time scale boundary layer theory to derive the equation of motion for a
dark (or ‘grey’) soliton propagating through an effectively one-dimensional cloud of Bose-Einstein condensate...
