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…
