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…

Direct observation of room-temperature exciton condensation
Jiaxin Yu, Guangyu Dai, Shuai Xing +6
Exciton condensation--an interaction-driven, macroscopically coherent paired-fermion state--offers the prospect for dissipationless energy transport in solids, akin to that in supe…
