Quasi-harmonic spectra from branched Hamiltonians

Aritra Ghosh, Bijan Bagchi, A. Ghose-Choudhury +2

We revisit the canonical quantization to assess the spectrum of the modified Emden equation $x ¨ + k x x ˙ + ω^{2} x + \frac{k ^{2}}{9} x^{3} = 0$ , which is an isochronous case of t…

Twin Hamiltonians, three types of the Dyson maps, and the probabilistic interpretation problem in quasi-Hermitian quantum mechanics

Aritra Ghosh, Adam Miranowicz, Miloslav Znojil

In the framework of the so-called quasi-Hermitian quantum mechanics of stationary unitary systems, bound states are usually constructed as eigenstates $∣ ψ_{n} ⟩$ of a Hamiltoni…

Isochronous oscillator with a singular position-dependent mass and its quantization

Aritra Ghosh, Bhabani Prasad Mandal, Bijan Bagchi

In this paper, we present an analysis of the equation $x ¨ - (1/2 x) x ˙^{2} + 2 ω^{2} x - 1/8 x = 0$ , where $ω > 0$ and $x = x (t)$ is a real-valued variable. We first discuss th…
