Self-referenced, drift-tolerant dipole-resolved population inversion using degeneracy-lifted dual quasinormal modes
Jiaxin Yu, Xinyu Zhang, Guangyu Dai +3
Photoluminescence intensity is widely used to infer exciton populations, yet the detected signal inherently convolves occupancy with radiative-rate modification and collection effi…

Calibrated Quantification of the Dark-Exciton Reservoir via a k-Space-Folding Probe
Guangyu Dai, Xinyu Zhang, Zhaoqi Gu +4
Spin-forbidden dark excitons in monolayer transition metal dichalcogenides constitute a dominant hidden reservoir that governs exciton dynamics and many-body interactions. Yet dete…
