Noncommutative Deformation of Optical States

In this paper, we study the noncommutative deformation of different optical states. We develop the deformed coherent state by using the raising and lowering operators of the quantum harmonic oscillator. This helps us to investigate the noncommutative deformation of a squeezed state in terms of noncommutative parameter, which in turn leads to the noncommutative deformation of a photon-added coherent state. This noncommutative deformation has an overall effect on the non-classicality of such states. This is done by investigating the impact of noncommutative deformation of the Mandal parameter for such states.

Quantization of Length in Spaces with Position-Dependent Noncommutativity

We present a novel approach to quantizing the length in noncommutative spaces with positional-dependent noncommutativity. The method involves constructing ladder operators that change the length not only along a plane but also along the third direction due to a noncommutative parameter that is a combination of canonical/Weyl-Moyal type and Lie algebraic type. The primary quantization of length in canonical-type noncommutative space takes place only on a plane, while in the present case, it happens in all three directions. We establish an operator algebra that allows for the raising or lowering of eigenvalues of the operator corresponding to the square of the length. We also attempt to determine how the obtained ladder operators act on different states and work out the eigenvalues of the square of the length operator in terms of eigenvalues corresponding to the ladder operators. We conclude by discussing the results obtained.
