Pseudo-Hermitian extensions of the harmonic and isotonic oscillators
Aritra Ghosh, Akash Sinha
In this work, we describe certain pseudo-Hermitian extensions of the harmonic and isotonic oscillators, both of which are exactly-solvable models in quantum mechanics. By coupling…

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…
