The Jaynes–Cummings model of a two-level atom in a single-mode para-Bose cavity field

Abstract The coherent states in the parity deformed analog of standard boson Glauber coherent states are generated, which admit a resolution of unity with a positive measure. The quantum-mechanical nature of the light field of these para-Bose states is studied, and it is found that para-Bose order p...
