Dissipation-induced nonreciprocal magnon blockade in a magnon-based hybrid system
Yimin Wang, Wei Xiong, Zhiyong Xu +2
We propose an experimentally realizable nonreciprocal magnonic device at the single-magnon level by exploiting magnon blockade in a magnon-based hybrid system. The coherent qubit-m…
Symmetry breaking and manipulation of nonlinear optical modes in an asymmetric double-channel waveguide
Rujiang Li, Fei Lv, Lu Li +1
We study light-beam propagation in a nonlinear coupler with an asymmetric double-channel waveguide and derive various analytical forms of optical modes. The results show that the s…
Nonlinear suppression of time-reversals in PT-symmetric optical couplers
Andrey A. Sukhorukov, Zhiyong Xu, Yuri S. Kivshar
We reveal a generic connection between the effect of time-reversals and nonlinear wave dynamics in systems with parity-time (PT) symmetry, considering a symmetric optical coupler w…
Complete spectral gap in coupled dielectric waveguides embedded into metal
Wei Liu, Andrey Sukhorukov, Andrey Miroshnichenko +4
We study a plasmonic coupler involving backward (TM_01) and forward (HE_11) modes of dielectric waveguides embedded into infinite metal. The simultaneously achievable contradirecti…
Interface solitons in quadratically nonlinear photonic lattices
Zhiyong Xu, Mario I. Molina, Yuri S. Kivshar
We study the properties of two-color nonlinear localized modes which may exist at the interfaces separating two different periodic photonic lattices in quadratic media, focussing o…
Spatial-Spectral Vortex Solitons in Quadratic Lattices
Zhiyong Xu, Andrey A. Sukhorukov
We predict the existence of spatial-spectral vortex solitons in one-dimensional periodic waveguide arrays with quadratic nonlinear response. In such vortices the energy flow forms…
Vector vortex solitons in nematic liquid crystals
Zhiyong Xu, Noel F. Smyth, Antonmaria A. Minzoni +1
We analyze the existence and stability of two-component vector solitons in nematic liquid crystals for which one of the components carries angular momentum and describes a vortex b…
