of a trapped soliton decreases almost monotonically, while the peak power of a trapped soliton increases monotonically. With the increase in ω or decrease in the absolute value of W0, the period and peak power ...
or loss term. We investigate the dynamics of bright-bright solitons , bright-dark solitons and dark-dark solitons for the time-dependent expulsive harmonic trap potential , periodically modulated harmonic ...
stabilize their propagation along the periodic potential . Our experiments demonstrate a generic mechanism for cluster-mediated transport with potential applications to condensed matter systems on different ...
. In general, the period of dark soliton oscillations in trapping potential depends on the specific conditions of the experiment and does not coincide with the oscillation period of a linear quantum-mechanical ...
and periodically modulated trap potentials , which can be experimentally realized in two-component condensates. These include periodic collapse and revival of solitons , and snake-like matter wave solitons as well ...
potential . First, we demonstrate analytically that, in the repulsive BEC, where the soliton is of the gap type, its effective mass is negative. This gives rise to a prediction for the experiment ...
We study discrete solitons (kinks) accessible in the state-of-the-art trapped ion experiments , considering zigzag crystals and quasi-three-dimensional configurations, both theoretically ...
excitations over an effective Dirac sea. The mismatch between the periodicities of potential and chain, giving rise to frustration, is a chemical potential whose amplitude is majorly determined by the Coulomb ...
