Dispersion Control of Chiral Exciton-Polariton Transport with Dielectric Metasurfaces
Juhyeong Jeon, Kehan Wang, Yu-Chen Wei +6
Exciton-polaritons provide a powerful platform for manipulating hybrid light-matter states with low effective masses and strong nonlinearities. Introducing chirality into these qua…

Probing phonon chirality and circular lattice motion with symmetry-selective nonlinear optical spectroscopy
Yuhan Wang, Yuxuan Wei, Li Huang +1
Truly chiral phonons are lattice eigenmodes that combine broken mirror symmetry with circular atomic motion. They can mediate angular-momentum-selective interactions in quantum mat…

Gate- and Optically Controlled Nonlinear Optical Response in Graphene via Non-Perturbative Ultrafast Carrier Dynamics
Xiaolong Lv, Yu Zhang, Yuxuan Wei +1
While the Dirac band structure of graphene has established it as a leading platform for ultrafast optoelectronics, its non-perturbative nonlinear response under intense excitation…
