Lax pairs and -matrices for some two-dimensional isotropic oscillators
Govind S. Krishnaswami, Garima Rajpoot, Srividya N. Vaidya
This paper concerns Lax pairs for circularly symmetric harmonic, Fock-Darwin-type and quartic anharmonic oscillators in two dimensions. Although the 2d isotropic harmonic oscillato…
Symbol sequences from three-rotor coincidences and their word-complexity
Govind S. Krishnaswami, Anirudh Rameshan
In the three-rotor problem, three equally massive point particles move on a circle interacting via attractive pairwise cosine potentials. Rotors can represent superconducting phase…
Level crossing instabilities in inviscid isothermal compressible Couette flow
Govind S. Krishnaswami, Sonakshi Sachdev, Pritish Sinha
We study the linear stability of inviscid steady parallel flow of an ideal gas in a channel of finite width. Compressible isothermal two-dimensional monochromatic perturbations are…
Quantum three-rotor problem in the identity representation
Govind S. Krishnaswami, Himalaya Senapati
The quantum three-rotor problem concerns the dynamics of 3 equally massive particles moving on a circle subject to pairwise attractive cosine potentials and can model coupled Josep…
Screwon spectral statistics and dispersion relation in the quantum Rajeev-Ranken model
Govind S. Krishnaswami, T. R. Vishnu
The Rajeev-Ranken (RR) model is a Hamiltonian system describing screw-type nonlinear waves (screwons) of wavenumber in a scalar field theory pseudodual to the 1+1D SU(2) princi…
Bifurcation cascade, self-similarity and duality in the 3-rotor problem
Govind S Krishnaswami, Ankit Yadav
The three-rotor system concerns equally massive point particles moving on a circle subject to attractive cosine potentials of strength . The quantum theory models chains of coup…
