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…

Population Metrology of a Hidden Exciton Reservoir: Quasi-Thermalization versus Localization
Guangyu Dai, Xinyu Zhang, Jiaxin Yu +8
Long-lived dark states can dominate the lowest-energy manifold of optically driven quantum materials, yet their occupation remains difficult to quantify, leaving it unclear whether…
