Signatures of valley drift in the diversified band dispersions of bright, gray, and dark excitons in MoS2 monolayers under uni-axial strains
Ching-Hung Shih, Guan-Hao Peng, Ping-Yuan Lo +4
We present a comprehensive theoretical investigation of the strain-modulated excitonic properties of uni-axially strained transition-metal dichalcogenide monolayers (TMD-MLs) by so…

Efficient light upconversion via resonant exciton-exciton annihilation of dark excitons in few-layer transition metal dichalcogenides
Yi-Hsun Chen, Ping-Yuan Lo, Kyle W. Boschen +15
In this work, we report a pronounced light upconversion in few-layer transition metal dichalcogenides. Our joint theory-experiment study attributes the upconversion photoluminescen…

Unveiling the nonclassicality within quasi-distribution representations through deep learning
Hong-Bin Chen, Cheng-Hua Liu, Kuan-Lun Lai +4
To unequivocally distinguish genuine quantumness from classicality, a widely adopted approach focuses on the negative values of a quasi-distribution representation as compelling ev…
