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…
