Generalized Liénard systems and isochronous connections
Bijan Bagchi, A. Ghose-Choudhury, Aritra Ghosh +1
In this paper, we explore some classical and quantum aspects of the nonlinear Liénard equation , where is a real variable…
First integrals of some two-dimensional integrable Hamiltonian systems
Aritra Ghosh, Akash Sinha, Bijan Bagchi
In this paper, we discuss some results on integrable Hamiltonian systems with two degrees of freedom. We revisit the much-studied problem of the two-dimensional harmonic oscillator…
Landauer's principle and black hole area quantization
Bijan Bagchi, Aritra Ghosh, Sauvik Sen
This article assesses Landauer's principle from information theory in the context of area quantization of the Schwarzschild black hole. Within a quantum-mechanical perspective wher…
Quantized Area of the Schwarzschild Black Hole: A non-Hermitian Perspective
Bijan Bagchi, Aritra Ghosh, Sauvik Sen
In this work, our aim is to link Bekenstein's quantized form of the area of the event horizon to the Hamiltonian of the non-Hermitian Swanson oscillator which is known to be $\math…
Generating QES potentials supporting zero energy normalizable states for an extended class of truncated Calogero Sutherland model
Satish Yadav, Sudhanshu Shekhar, Bijan Bagchi +1
Motivated by recent interest in the search for generating potentials for which the underlying Schrödinger equation is solvable, we report in the recent work several situations when…
A reappraisal of Lagrangians with non-quadratic velocity dependence and branched Hamiltonians
Bijan Bagchi, Aritra Ghosh, Miloslav Znojil
Time and again, non-conventional forms of Lagrangians with non-quadratic velocity dependence have found attention in the literature. For one thing, such Lagrangians have deep conne…
Exceptional points and quantum phase transition in a fermionic extension of the Swanson oscillator
Akash Sinha, Aritra Ghosh, Bijan Bagchi
Motivated by the structure of the Swanson oscillator which is a well-known example of a non-Hermitian quantum system consisting of a general representation of a quadratic Hamiltoni…
