Decoherence of Deformed Photon Added Coherent State
Amit Das, Sobhan Sounda
In this study, we explore the behavior of photon added coherent states in a deformed harmonic oscillator subjected to dissipative decoherence. We use deformation as our nonline…

Comprehensive Analysis of Geometric Phase for SU(3) Representations
Abhirup Chatterjee, Sobhan Kumar Sounda
Geometric Phase in Quantum Mechanics is generally formulated entirely in terms of geometric structure of the Complex Hilbert Space. We will exploit this fact in case of mixed state…

Nonclassicality and sub-Planck structures of photon subtracted compass states
Amit Das, Sobhan Sounda
We discuss the nonclassical properties of photon-subtracted compass states (PSCS). Nonclassical behavior is studied using various parameters like the Wigner function, squeezing, an…
