Spatial Focusing of Surface Polaritons Based on Cross-Phase Modulation
Chaohua Tan, Na Li, Datang Xu +2
We theoretically study the spatial focusing of surface polaritons (SPs) in a negative index metamaterial (NIMM)-atomic gas interface waveguide system, based on cross phase modulati…

Anisotropic longitudinal optical conductivities of tilted Dirac bands in 1T-MoS
Chao-Yang Tan, Chang-Xu Yan, Yong-Hong Zhao +2
1T-MoS exhibits valley-spin-polarized tilted Dirac bands in the presence of external vertical electric field and undergoes a topological phase transition between the t…

Low-loss Airy Surface Plasmon Polaritons
Qi Zhang, Chaohua Tan, Chao Hang +1
We propose a scheme to obtain a low-loss propagation of Airy surface plasmon polaritons (SPPs) along the interface between a dielectric and a negative-index metamaterial (NIMM). We…
