Nonclassical properties of ‘semi-coherent’ quantum states
V. V. Dodonov, M.B. Renó · Journal of Physics A Mathematical and General · 2006
We study the properties of ‘semi-coherent’ quantum states introduced by Mathews and Eswaran in 1973, establishing relations between them and other families of ‘nonclassical’ states, such as displaced number states and ‘multiphoton’ states. We also analyse the photon number distribution, photon statistics, the Wigner and marginal distribution functions, and show the ways for possible further generalizations.
