Quasi-integrability from PT-symmetry
Kumar Abhinav, Partha Guha, Indranil Mukherjee
Parity and time-reversal (PT ) symmetry is shown as the natural cause of quasi-integrability of deformed integrable models, crucial to represent real physical systems as they posse…
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 , which is an isochronous case of…
On novel Hamiltonian descriptions of some three-dimensional non-conservative systems
Aritra Ghosh, Anindya Ghose-Choudhury, Partha Guha
We present novel Hamiltonian descriptions of some three-dimensional systems including two well-known systems describing the three-wave-interaction problem and some well-known chaot…
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 variab…
