Theory of a dipolar quantum gas in a multi-well potential — •David Peter1, Krzysztof Pawłowski2, Kazimierz Rzazewski2, and Tilman Pfau1 — 15. Physikalisches Institut, Universität Stuttgart — 2Center for Theoretical Physics, Polish Academy of Sciences, Warsaw
We investigate the physics of dipolar bosons in a multi-well potential, generalizing what has been done for the triple-well system in [1]. Due to the non-local character of the dipolar interaction and the finite size of the system, inter-site effects are crucial and lead to a large variety of ground states – some of them not being apparent in the triple-well system. These calculations are also applicable to the situation where a dipolar Bose-Einstein condensate is loaded into a 1D optical lattice with a large number of sites occupied.
