Topology-induced spatial Bose–Einstein condensation for bosons on star-shaped optical networks
Topology-induced spatial Bose–Einstein condensation for bosons on star-shaped optical networks
New coherent states may be induced by pertinently engineering the topology of a network. As an example, we consider the properties of non-interacting bosons on a star network, which may be realized with a dilute atomic gas in a star-shaped deep optical lattice. The ground state is localized around the …
