. For example, the work [16] consider Bose atoms in a finite 1D lattice, where the first and last sites of the lattice are coupled to reservoirs of cold atoms. Theoretically this is done by introducing the Lindblad operators, which supply atoms into the first...
, it is not clear in advance to which extent the used Lindblad operators are justified. To clarify these questions we need a microscopic model of the source and sink. In the present work we analyze one of possible microscopic models of the source/sink, which...
