Absorption Reduction of Large Purcell Enhancement Enabled by Topological State-Led Mode Coupling.
Zhiyuan Qian,Zhichao Li,He Hao,Lingxiao Shan,Qi Zhang,Jian-Wen Dong,Qihuang Gong,Qihuang Gong,Ying Gu,Ying Gu +9 more
TL;DR: In this article, the authors proposed the edge state-led mode coupling under topological protection, i.e., localized surface plasmons almost do not have any influence on the edge states, while the edge-state greatly changes the local field distribution of surface plasms.

Electromagnetically and optomechanically induced transparency and amplification in an atom-assisted cavity optomechanical system
He Hao,Mark C. Kuzyk,Juanjuan Ren,Fan Zhang,Xueke Duan,Ling Zhou,Tiancai Zhang,Qihuang Gong,Hailin Wang,Ying Gu +9 more
TL;DR: In this article, an atom-assisted cavity optomechanical system consisting of a single $\mathrm{\ensuremath{\Lambda}}$-type three-level atom, a mechanical resonator, and a sideband-driven cavity is presented.

Large Purcell enhancement with efficient one-dimensional collection via coupled nanowire-nanorod system.
Xueke Duan,Juanjuan Ren,Fan Zhang,He Hao,Guowei Lu,Guowei Lu,Qihuang Gong,Qihuang Gong,Ying Gu,Ying Gu +9 more
TL;DR: This proposal that incorporates large Purcell enhancement, efficient nanoscale collection and one-dimensional propagation of photons, promises to have an important impact on bright single photon sources, plasmon-based nanolasers and on-chip nanodevices.

A quantum phase gate capable of effectively collecting photons based on a gap plasmon structure.
TL;DR: This work theoretically demonstrate a quantum phase gate, simultaneously achieving an arbitrary phase shift and effective photon collection at the nanoscale, and may act as universal quantum nodes that can process and store quantum information.

High-dielectric constant enhanced photon–exciton coupling in an evanescent vacuum
TL;DR: In this article, a high dielectric constant enhanced photon-exciton coupling was investigated by embedding a nanocavity quantum electrodynamic system in an evanescent vacuum, and the enhanced coupling coefficients were also demonstrated by changing the Ag nanorod size and the gap distance between the nanoparticle and plate.
