We present an experimentally--accessible entanglement criterion witnessing collective
entanglement among lattice sites. It can be measured through Raman scattering or time-of …

We study different representations of a many-particle system. We reveal the connections
among the nonclassicalities of many-particle, single-mode and two-mode systems in the …

A binary mixture of Bose-Einstein condensate structures exhibits an incredible richness in
terms of holding different kinds of phases. Depending on the ratio of the inter-and intra …
