Realization of all-optical vortex switching in exciton-polariton condensates
Xuekai Ma, Bernd Berger, Marc Assmann +5
Vortices are topological objects representing the circular motion of a fluid. With their additional degree of freedom, the 'vorticity', they have been widely investigated in many p…
Observation and uses of position-space Bloch oscillations in an ultracold gas
Zachary A. Geiger, Kurt M. Fujiwara, Kevin Singh +8
We report the direct observation and characterization of position-space Bloch oscillations using an ultracold gas in a tilted optical lattice. While Bloch oscillations in momentum…
Nonlinearity-induced localization in a periodically-driven semi-discrete system
R. Driben, V. V. Konotop, B. A. Malomed +2
We demonstrate that nonlinearity plays a constructive role in supporting the robustness of dynamical localization in a model which is discrete, in one dimension and continuous in t…
Dispersive radiation and regime switching of oscillating bound solitons in twin-core fibers near zero-dispersion wavelength
Ivan Oreshnikov, Rodislav Driben, Alexey Yulin
We study resonant radiation generated by bound solitons in a twin-core fiber near zero-dispersion wavelength, in the presence of higher order dispersion terms. We propose a theoret…
Two-dimensional symbiotic solitons and vortices in binary condensates with attractive cross-species interaction
Xuekai Ma, Rodislav Driben, Boris A. Malomed +2
We consider a two-dimensional (2D) two-component spinor system with cubic attraction between the components and intra-species self-repulsion, which may be realized in atomic Bose-E…
Dynamics of dipoles and vortices in nonlinearly-coupled three-dimensional harmonic oscillators
R. Driben, V. V. Konotop, B. A. Malomed +1
The dynamics of a pair of three-dimensional matter-wave harmonic oscillators (HOs) coupled by a repulsive cubic nonlinearity is investigated through direct simulations of the respe…
