Dark Solitary Waves in a Class of Collisionally Inhomogeneous Bose-Einstein Condensates
Chang Wang, Kody J. H. Law, Panayotis. G. Kevrekidis +1
We study the structure, stability, and dynamics of dark solitary waves in parabolically trapped, collisionally inhomogeneous Bose-Einstein condensates (BECs) with spatially periodi…
Mapping Between Generalized Nonlinear Schroedinger Equations and Neutral Scalar Field Theories and New Solutions of the Cubic-Quintic NLS Equation
Avinash Khare, Avadh Saxena, Kody J. H. Law
We highlight an interesting mapping between the moving breather solutions of the generalized Nonlinear Schrodinger (NLS) equations and the static solutions of neutral scalar field…
Stable structures with high topological charge in nonlinear photonic quasicrystals
K. J. H. Law, Avadh Saxena, P. G. Kevrekidis +1
Stable vortices with topological charge of 3 and 4 are examined numerically and analytically in photonic quasicrystals created by interference of 5 as well as 8 beams, in the cases…
Stable Vortex-Bright Soliton Structures in Two-Component Bose Einstein Condensates
K. J. H. Law, P. G. Kevrekidis, Laurette S. Tuckerman
We report the numerical realization and demonstration of robustness of certain 2-component structures in Bose-Einstein Condensates in 2 and 3 spatial dimensions with non-trivial to…
Existence and stability of multisite breathers in honeycomb and hexagonal lattices
V. Koukouloyannis, P. G. Kevrekidis, K. J. H. Law +2
We study the existence and stability of multisite discrete breathers in two prototypical non-square Klein-Gordon lattices, namely a honeycomb and a hexagonal one. In the honeycomb…
A two-dimensional paradigm for symmetry breaking: the nonlinear Schrodinger equation with a four-well potential
C. Wang, G. Theocharis, P. G. Kevrekidis +4
We study the existence and stability of localized states in the two-dimensional (2D) nonlinear Schrodinger (NLS)/Gross-Pitaevskii equation with a symmetric four-well potential. Usi…
