A method to solve nonlinear Schrödinger equation using Riccati equation
Vivek M. Vyas, Rama Gupta, C. N. Kumar +1
A method to find exact solutions to nonlinear Schrödinger equation, defined on a line and on a plane, is found by connecting it with second order linear ordinary differential equat…
Some results on topological currents in field theory
Vivek M. Vyas, V. Srinivasan, Prasanta K. Panigrahi
A few exact results concerning topological currents in field theories are obtained. It is generally shown that, a topological charge can not generate any kind of symmetry transform…
Simultaneous weak value amplification of angular Goos-Hänchen and Imbert-Fedorov shifts in partial reflection
Sumit Goswami, Mandira Pal, Arindam Nandi +2
The optical analogue of quantum weak measurements have shown considerable promise for the amplification and observation of tiny optical beam shifts, namely, the Goos-Hänchen (GH) a…
Rogue solitons in Heisenberg spin chain
Aritra K. Mukhopadhyay, Vivek M. Vyas, Prasanta K. Panigrahi
Following the connection of the non-linear Schrödinger equation with the continuum Heisenberg spin chain, we find the rogue soliton equivalent in the spin system. The breathers are…
Multi-scale dynamics of glow discharge plasma through wavelets: Self-similar behavior to neutral turbulence and dissipation
Bapun K. Giri, Chiranjit Mitra, Prasanta K. Panigrahi +1
The multiscale dynamics of glow discharge plasma is analysed through wavelet transform, whose scale dependent variable window size aptly captures both transients and non-stationary…
