On the -symmetric parametric amplifier
Pinaki Patra
Parametric amplifiers are an integral part of measurements involving the conversion of propagating quantum information to mechanical motion. General time-dependent PT-symmetric par…
Tuning the separability in noncommutative space
Pinaki Patra
We study the Separability of the noncommutative (NC) space coordinate degrees of freedom with the generalized Peres-Horodecki separability criterion (Simon's condition) for a bipar…
Generalized coherent states and uncertainty relations in -symmetric position dependent mass systems
Pinaki Patra
In this paper, we investigate a class of PT-symmetric quantum systems with position-dependent effective mass (PDEM). We factorize the PDEM Hamiltonian using a pair of generalized a…
Dynamics of free time-dependent effective mass
Pinaki Patra, Aditi Chowdhury, Milan Jana
The consensus is that an object with a large mass will not manifest quantum behavior. Therefore, we expect that the quantumness of a time-dependent effective mass (TDEM) will erase…
On the two-dimensional time-dependent anisotropic harmonic oscillator in a magnetic field
Pinaki Patra
A Charged harmonic oscillator in a magnetic field, Landau problems, and an oscillator in a noncommutative space, share the same mathematical structure in their Hamiltonians. We hav…
Entanglement in phase-space distribution for an anisotropic harmonic oscillator in noncommutative space
Pinaki Patra
The bi-partite Gaussian state, corresponding to an anisotropic harmonic oscillator in a noncommutative-space, is investigated with the help of the Simon's separability condition (g…
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…
Modified Hamiltonian formalism for Regge Teitelboim Cosmology
Pinaki Patra, Md. Raju, Gargi Manna +1
The Ostrogradski approach for the Hamiltonian formalism of higher derivative theory is not satisfactory because of the reason that the Lagrangian cannot be viewed as a function on…
Quantum Restoration of Broken Symmetry in one Dimensional Loop Space
Pinaki Patra, Tanmay Mandal, Jyoti Prasad Saha
For 1 Dimensional loop space, a nonlinear nonlocal transformation of fields is given to make the action of the self-interacting quantum field to the free one. A specific type of Cl…
Current conservation in charge conjugation parity time reversal symmetry (CPT) violating gauge-invariant nonlocal Thirring model
Pinaki Patra, Jyoti Prasad Saha
Charge conjugation, parity transformation and time reversal symmetry (CPT) violation and Lorentz invariance can coexist in the framework of non-local field theory. In this article…

It is possible to construct Lorentz invariant CPT violating models for Nonlocal Quantum Field Theory. In this article, we present a class of Nonlocal Thirring Models, in which the…
Uncertainty principle certifies genuine source of intrinsic randomness
Trina Chakraborty, Manik Banik, Pinaki Patra
The Born's rule introduces intrinsic randomness to the outcomes of a measurement performed on a quantum mechanical system. But, if the system is prepared in the eigenstate of an ob…
Engineering light localization in a fractal waveguide network
Biplab Pal, Pinaki Patra, Jyoti Prasad Saha +1
We present an exact analytical method of engineering the localization of electromagnetic waves in a fractal waveguide network. It is shown that, a countable infinity of localized e…
