We consider the transfer of lattice wave packets through a tilted discrete breather (TDB) in opposite directions in the discrete nonlinear Schrödinger model with asymmetric defects, which may be realized as a Bose-Einstein condensate trapped in a deep optical lattice, or as optical beams in a waveguide array. A unidirectional transport mode is found, in which the incident wave packets, whose energy belongs to a certain interval between full reflection and full passage regions, pass the TDB only…

There is a higher transmission for incoming waves with lower wavenumber as compared to the waves with comparatively larger wavenumbers and a diode-like effect improves by increasing the nonlinear layers and the cooperation between cubic and quintic nonlinear response is not “additive”.

It is found that tuning the spin orientation of the localized Bose-Einstein condensate can lead to spin-nonreciprocal/spin-Reciprocal transport, meaning the transport properties are dependent on/independent of the spin Orientation of incident waves.

- Computer Science
- 2018

A scheme to implement quantum state engineering in a four-state system via counterdiabatic driving finds that a fast QSE can be realized by utilizing simply designed pulses, and shows that the multi-mode driving method seems to have a wider range of applications than the single- mode driving method with respect to different parameters.
