Dynamics, dephasing and clustering of impurity atoms in Bose-Einstein condensates
Alexander Klein, Martin Bruderer, Stephen R. Clark +1
We investigate the influence of a Bose-Einstein condensate (BEC) on the properties of immersed impurity atoms, which are trapped in an optical lattice. Assuming a weak coupling of…

Transport of strong-coupling polarons in optical lattices
M. Bruderer, A. Klein, S. R. Clark +1
We study the transport of ultracold impurity atoms immersed in a Bose-Einstein condensate (BEC) and trapped in a tight optical lattice. Within the strong-coupling regime, we derive…
