Application of an inverse Holstein-Primakoff transformation to the Jaynes-Cummings model
Carla Maria Pontes Carneiro, Giancarlo Queiroz Pellegrino
A modification of the Holstein-Primakoff transformation is proposed such that creation and annihilation operators for a bosonic field are rewritten as operators of a algebr…
