Vortex solitons in twisted circular waveguide arrays
Liangwei Dong, Yaroslav V. Kartashov, Lluis Torner +1
We address the formation of topological states in twisted circular waveguide arrays and find that twisting leads to important differences of the fundamental properties of new vorte…
A method for the dynamics of vortices in a Bose-Einstein condensate: analytical equations of the trajectories of phase singularities
S. de María-García, A. Ferrando, J. A. Conejero +2
We present a method to study the dynamics of a quasi-two dimensional Bose-Einstein condensate which contains initially many vortices at arbitrary locations. We present first the an…
Topological edge states of nonequilibrium polaritons in hollow honeycomb arrays
Xuekai Ma, Yaroslav V. Kartashov, Albert Ferrando +1
We address topological currents in polariton condensates excited by uniform resonant pumps in finite honeycomb arrays of microcavity pillars with a hole in the center. Such current…
Nonlinear higher-order polariton topological insulator
Yiqi Zhang, Y. V. Kartashov, L. Torner +2
We address the resonant response and bistability of the exciton-polariton corner states in a higher-order nonlinear topological insulator realized with kagome arrangement of microc…
Interface states in polariton topological insulators
Yiqi Zhang, Yaroslav V. Kartashov, Albert Ferrando
We address linear and nonlinear topological interface states in polariton condensates excited at the interface of the honeycomb and Lieb arrays of microcavity pillars in the presen…
Graded-index optical fiber emulator of an interacting three-atom system: illumination control of particle statistics and classical non-separability
M. A. Garcia-March, N. L. Harshman, H. da Silva +4
We show that a system of three trapped ultracold and strongly interacting atoms in one-dimension can be emulated using an optical fiber with a graded-index profile and thin metalli…
