Stable higher-charge discrete vortices in hexagonal optical lattices
Kody J. H. Law, P. G. Kevrekidis, Tristram J. Alexander +2
We show that double-charge discrete optical vortices may be completely stable in hexagonal photonic lattices where single-charge vortices always exhibit dynamical instabilities. Ev…
Solitons and vortices in honeycomb defocusing photonic lattices
K. J. H. Law, H. Susanto, P. G. Kevrekidis
Solitons and necklaces in the first band-gap of a two-dimensional optically induced honeycomb defocusing photonic lattice are theoretically considered. It is shown that dipoles, so…
Dipole and quadrupole solitons in optically-induced two-dimensional defocusing photonic lattices
H. Susanto, K. Law, P. G. Kevrekidis +4
Dipole and quadrupole solitons in a two-dimensional optically induced defocus- ing photonic lattice are theoretically predicted and experimentally observed. It is shown that in-pha…
Stability of Quantized Vortices in a Bose-Einstein Condensate Confined in an Optical Lattice
K. J. H. Law, L. Qiao, P. G. Kevrekidis +1
We investigate the existence and especially the linear stability of single and multiple-charge quantized vortex states of nonlinear Schroedinger equations in the presence of a peri…
Structure and stability of two-dimensional Bose-Einstein condensates under both harmonic and lattice confinement
K. J. H. Law, P. G. Kevrekidis, B. P. Anderson +2
In this work, we study pancake-shaped Bose-Einstein condensates confined by both a cylindrically symmetric harmonic potential and an optical lattice with equal periodicity in two o…
