Coherent state of a nonlinear oscillator and its revival dynamics
Bikashkali Midya, Barnana Roy, Atreyee Biswas
The coherent state of a nonlinear oscillator having a nonlinear spectrum is constructed using Gazeau Klauder formalism. The weighting distribution and the Mandel parameter are stud…
A generalized quantum nonlinear oscillator
Bikashkali Midya, Barnana Roy
We examine various generalizations, e.g. exactly solvable, quasi-exactly solvable and non-Hermitian variants, of a quantum nonlinear oscillator. For all these cases, the same mass…
Exceptional orthogonal polynomials and exactly solvable potentials in position dependent mass Schroedinger Hamiltonians
Bikashkali Midya, Barnana Roy
Some exactly solvable potentials in the position dependent mass background are generated whose bound states are given in terms of Laguerre- or Jacobi-type exceptional orthogo…
Quantum dot with spin-orbit interaction in noncommutative phase space and analog Landau levels
B. K. Pal, B. Roy, B. Basu
We have studied a quantum dot with Rashba spin orbit interaction on a plane where the position and momentum coordinates are considered to be noncommutative. The energy spectrum of…
Coherent state of the effective mass harmonic oscillator
Atreyee Biswas, Barnana Roy
We construct coherent state of the effective mass harmonic oscillator and examine some of its properties. In particular closed form expressions of coherent states for different cho…
