Optical Thermodynamics Beyond the Weak Nonlinearity Limit
Emily Kabat, Shrohan Mohapatra, P. G. Kevrekidis +1
Optical thermodynamics has recently emerged as a theoretical framework describing a Rayleigh-Jeans (RJ) modal power distribution of multimoded nonlinear photonic circuits. However,…

Dam breaks in the discrete nonlinear Schrödinger equation
Shrohan Mohapatra, Panayotis G. Kevrekidis, Su Yang +1
In the present work we study the nucleation of Dispersive shock waves (DSW) in the {defocusing}, discrete nonlinear Schr{ö}dinger equation (DNLS), a model of wide relevance to non…

The vortex comb: eliminating vortices from Bose-Einstein condensates using optical lattices
Shrohan Mohapatra, Andrew J. Schaffer, P. G. Kevrekidis +2
In the present work we introduce and explore a technique for the efficient removal of vortices from an atomic Bose-Einstein condensate, through the application and subsequent remov…
