Popis:	The fate of the single particle immersed in and interacting with a bath of other particles localized in a tilted lattice is investigated. For tilt values comparable to the tunneling rate a slow-down of the dynamics is observed without, however, a clear localization of the impurity. For large tilt and strong interactions the motion of the impurity resembles that in the Kronig-Penney potential. The dynamics depends on the initial distribution of tilted bosons. It shows delocalized dynamics for a regular, density wave like distribution and a localization if tilted bosons are randomly distributed. Comment: 12 pp.version close to accepted in PRB
