Solitons under spatially localized cubic-quintic-septimal nonlinearities
H. Fabrelli, J. B. Sudharsan, R. Radha +2
We explore stability regions for solitons in the nonlinear Schrodinger equation with a spatially confined region carrying a combination of self-focusing cubic and septimal terms, w…
Faraday and resonant waves in binary collisionally-inhomogeneous Bose-Einstein condensates
J. B. Sudharsan, R. Radha, Mihaela Carina Raportaru +2
We study Faraday and resonant waves in two-component quasi-one-dimensional (cigar-shaped) collisionally inhomogeneous Bose-Einstein condensates subject to periodic modulation of th…
Stable multiple vortices in collisionally inhomogeneous attractive Bose-Einstein condensates
J. B. Sudharsan, R. Radha, H. Fabrelli +2
We study stability of solitary vortices in the two-dimensional trapped Bose-Einstein condensate (BEC) with a spatially localized region of self-attraction. Solving the respective B…
Engineering Bright Solitons to Enhance the Stability of Two-Component Bose-Einstein Condensates
R. Radha, P. S. Vinayagam, J. B. Sudharsan +2
We consider a system of coupled Gross-Pitaevskii (GP) equations describing a binary quasi-one-dimensional Bose-Einstein condensate (BEC) with intrinsic time-dependent attractive in…
Persistent bright solitons in sign-indefinite coupled nonlinear Schrodinger equations with a time-dependent harmonic trap
R. Radha, P. S. Vinayagam, J. B. Sudharsan +1
We introduce a model based on a system of coupled nonlinear Schrodinger (NLS) equations with opposite signs infront of the kinetic and gradient terms in the two equations. It also…
Collisionally inhomogeneous Bose-Einstein condensates with binary and three body interactions in a bichromatic optical lattice
J. B. Sudharsan, R. Radha, P. Muruganandam
We study the impact of collisionally inhomogeneous binary and three body interaction on Bose-Einstein condensates (BECs) of a dilute gas in a bichromatic optical lattice. We observ…
