Phase space picture of Morse-like coherent states based upon the Wigner function
O de los Santos-Sánchez, J. Récamier
Abstract
Using the Wigner distribution function, we analyze the behavior on phase space of generalized coherent states associated with the Morse potential (Morse-like coherent states). Within the f -deformed oscillator formalism, such states are constructed by means of the following two definitions: (i) as deformed displacement operator coherent states and (ii) as deformed photon-added coherent states.
