Quantum Optics Nature of the Elementary Excitations in Few-Layer WSe2 Semiconductors
Ji Zhou, Yitong Wang, Debao Zhang +5
A fully quantized description of a two-level system resonantly coupled with an electromagnetic field (light) is among the central topics of quantum electrodynamics, which is theori…
Odd-Parity Selection in Parity-Forbidden Electronic Transitions Revealed by Mn4+ Fluorescence Spectroscopy
Yitong Wang, Fei Tang, Jiqiang Ning +1
Mn4+-doped fluoride phosphors represent a significant class of narrow band red-emitting materials, whose luminescent properties are profoundly influenced by electron-phonon couplin…
Temperature dependence of quasi-localized phonons-mediated non-Markovianity dynamics of SiV^- centers in diamond
Wanggui Ye, Debao Zhang, Xuguang Cao +6
Here we investigate the temperature-dependent non-Markovian dynamics of the SiV^- center in diamond, focusing on the roles of low- and high-frequency quasi-localized phonon modes.…
Brightening dark trions in WS2 monolayers via introducing atomic sulfur vacancies
Xuguang Cao, Wanggui Ye, Debao Zhang +7
Understanding the effects of atomic defects on the optical functionality of two-dimensional (2D) layered materials is critical to develop novel optical and optoelectronic applicati…
Tunability of Robust Exciton-Trion Polaritons in Atomically Thin WS2 Monolayers
Xuguang Cao, Debao Zhang, Ji Zhou +6
Herein, we present an experimental demonstration of the robust exciton-trion polaritons (ETPs) by measuring and simulating the resonance reflectance spectra of various configuratio…
