Single-mode nonclassicality criteria via Holstein–Primakoff transformation
Single-mode nonclassicality criteria via Holstein–Primakoff transformation
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 infinite particle number limit. First, we demonstrate that (separable) atomic coherent states, of a many-particle system, mimic the coherent states of single-mode light as the number of …
