Generalized quantum theory for accessing nonlinear systems: the case of LiÃ©nard and Levinson-Smith equations

Bijan Bagchi, Anindya Ghose-Choudhury

We show that a recently introduced generalized scheme of quantum mechanics has connections to LiÃ©nard and Levinson-Smith classes of nonlinear systems. For the LiÃ©nard type, which…

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 $x ¨ + k x x ˙ + I ¨ ^{2} x + \frac{k ^{2}}{9} x^{3} = 0$ , which is an isochronous case of…

In this paper, we explore some classical and quantum aspects of the nonlinear LiÃ©nard equation $x ¨ + k x x ˙ + I ¨ ^{2} x + (k^{2} /9) x^{3} = 0$ , where $x = x (t)$ is a real variab…
