Ground-state properties of few dipolar bosons in a quasi-one-dimensional harmonic trap

Deuretzbacher, Frank; Cremon, J.C.; Reimann, S.M. (College Park, MD : American Physical Society, 2010)

We study the ground state of few bosons with repulsive dipole-dipole interaction in a quasi-one-dimensional harmonic trap by means of the exact diagonalization method. Up to three interaction regimes are found, depending ...
Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field

Greschner, Sebastian; Piraud, M.; Heidrich-Meisner, F.; McCulloch, I.P.; Schollwöck, U.; Vekua, T. (College Park, MD : American Physical Society, 2016)

We study the quantum phases of bosons with repulsive contact interactions on a two-leg ladder in the presence of a uniform Abelian gauge field. The model realizes many interesting states, including Meissner phases, vortex ...
