Squeezed coherent states for gravitational well in noncommutative space

Kalpana Biswas, Jyoti Prasad Saha, Pinaki Patra

Gravitational well is a widely used system for the verification of the quantum weak equivalence principle (WEP). We have studied the quantum gravitational well (GW) under the shed…

Entropy uncertainty principle for Dirac system with mass jump

Pinaki Patra, Kalpana Biswas

Dependency on the preparation of state for the Heisenberg uncertainty principle can be removed with the help of entropy uncertainty principle. The shortness of the uncertainty prin…

Generalized Lewis-Riesenfeld invariance for dynamical effective mass in jammed granullar media under a potential well in non-commutative space

Kalpana Biswas, Jyoti Prasad Saha, Pinaki Patra

Consideration of the asteroid belt (Kuiper belt) as a jammed-granular media establishes a bridge between condensed matter physics and astrophysics. It opens up an experimental poss…

Constraints on the choice of position dependent effective mass and external potential for the existence of Lewis-Riesenfeld invariance and quantum canonical transformation

Kalpana Biswas, Jyoti Prasad Saha, Pinaki Patra

Lewis-Riesenfeld -Ermakov's (LR) invariant method for the construction of time-dependent phase-space invariant is extended for the general quantum system with position-dependent ef…

On the position dependent effective mass Hamiltonian

Kalpana Biswas, Jyoti Prasad Saha, Pinaki Patra

Noncommutivity of position and momentum makes it difficult to formulate the unambiguous structure of the kinetic part of Hamiltonian for the position-dependent effective mass (PDEM…

Self-adjoint extension for Maxwell-Chern-Simons model in long wavelength limit

Pinaki Patra, Jyoti Prasad Saha, Kalpana Biswas

In the long wavelength limit, Maxwell-Chern-Simmon model and the dynamics of a particle in a plane under an external magnetic field perpendicular to that plane are identical. The s…
