Construction of Some Important Classes of Generalized Coherent states Through Nonlinear Coherent States

R. Roknizadeh, Mohammad Kazem Tavassoly

Considering some important classes of generalized coherent states, we demonstrated that all of them can be created using the "lowering operator eigenstate" and the "displacement operator" techniques through viewing these states as nonlinear coherent states.

The construction of some important classes of generalized coherent states: the nonlinear coherent states method

R. Roknizadeh, Mohammad Kazem Tavassoly

Considering some important classes of generalized coherent states known in literature, we demonstrated that all of them can be created via conventional fashion, i.e. the "lowering operator eigen-state" and the "displacement operator" techniques using the {\it "nonlinear coherent states"} approach. As a result we obtained a {\it "unified method"} to construct a large class of coherent states which already have been introduced by different prescriptions.

New nonlinear coherent states and some of their nonclassical properties

B Roy, P Roy

We construct a displacement-operator-type nonlinear coherent state and examine some of its properties. In particular, it is shown that this nonlinear coherent state exhibits nonclassical properties such as squeezing and sub-Poissonian behaviour.

Nonlinear coherent states for the Susskind-Glogower operators

León-Montiel, Roberto de Jesús, Moya-Cessa, Hector Manuel, Francisco Soto

We construct nonlinear coherent states for the Susskind-Glogower operators by the application of the displacement operator on the vacuum state. We also construct nonlinear coherent states as eigenfunctions of a Hamiltonian constructed with the Susskind-Glogower operators. We generalize the solution of the eigen- function problem to an arbitrary |mi initial condition. To analyze the obtained results, we plot the Husimi Q function, the photon number probability distribution and the Mandel Q-parameter. For both cases, we find that the constructed states exhibit interesting nonclassical features, such as amplitude squeezing and quantum interferences due to a self-splitting into two coherent-like states. Additionally, we show that non- linear coherent states may be modeled by propagating light in semi-infinite arrays of optical fibers.

We generalize the solution\nto the eigenfunction problem to an arbitrary jmi initial condition. To analize\nthe obtained results, we plot the Husimi Q function, the photon number\nprobability distribution and the Mandel Q-parameter. For both cases, we nd\nthat the constructed states exhibit interesting nonclassical features such as\namplitude squeezing and quantum inteferences due to a self-splitting into two\ncoherent-like states.
