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… 
Matter-wave soliton buffer realized by a tailored one-dimensional lattice
By introducing the attractive dipole–dipole interaction, we provide a proposal to buffer the matter-wave soliton in a one-dimensional discrete lattice, which is divided into three parts with
Unidirectional flow of discrete solitons in optical waveguide arrays with nonlinearity management
Abstract We propose a mechanism for realising a unidirectional flow of discrete solitons in optical waveguide arrays. Modulating the nonlinear interaction strength in each waveguide according to a
Asymmetric wave transmission through one dimensional lattices with cubic-quintic nonlinearity
TLDR
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”.
Unidirectional flow of composite bright-bright solitons through asymmetric double potential barriers and wells
TLDR
A comparative study between analytical and numerical analysis lead to an excellent agreement between the two methods and a novel phenomenon which is named “Polarity Reversal” in the unidirectional flow.
Tunable spinful matter wave valve
TLDR
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.
Transient diffusion and two-regime localization of discrete breatherlike excitations in nonlinear Schrödinger lattice with disorder.
TLDR
This study systematically simulate and analyze the motion of discrete breatherlike excitations in the nonlinear Schrödinger lattice with random potentials to shed light on understanding the interplay between disorder and strong nonlinearity, from the diffusive transport and localization properties of nonlinear localized excitation in random media.
Asymmetric nonlinear system is not sufficient for a nonreciprocal wave diode
We demonstrate symmetric wave propagations in asymmetric nonlinear quantum systems. By solving the nonlinear Sch\"ordinger equation, we first analytically prove the existence of symmetric
Phase-controlled single-photon nonreciprocal transmission in a one-dimensional waveguide
We study the controllable single-photon scattering via a one-dimensional waveguide which is coupled to a two-level emitter and a single-mode cavity simultaneously. The emitter and the cavity are also
Tunable quantum switcher and router of single atoms using localized artificial magnetic fields
We investigate the single-atom transport in a two-leg ladder with only two rungs, which together with the legs, enclose an artificial magnetic flux. Here, the atoms on the two legs possess opposite
Efficient implementation of arbitrary quantum state engineering in four-state system by counterdiabatic driving
TLDR
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.
