Observing the Birth of Rydberg Exciton Fermi Polarons on a Moire Fermi Sea
Eric A. Arsenault, Gillian E. Minarik, Jiaqi Cai +8
The optical spectra of two-dimensional (2D) semiconductors are dominated by tightly bound excitons and trions. In the low doping limit, trions are often described as three-body qua…
Optical control of orbital magnetism in magic angle twisted bilayer graphene
Eylon Persky, Minhao He, Jiaqi Cai +4
Flat bands in graphene-based moiré structures host a wide range of emerging strongly correlated and topological phenomena. Optically probing and controlling them can reveal importa…
Dynamically tunable moiré Rydberg excitons in a monolayer semiconductor on twisted bilayer graphene
Minhao He, Jiaqi Cai, Huiyuan Zheng +8
Moiré excitons are emergent optical excitations in 2D semiconductors with deep moiré superlattice potentials. While these excitations have been realized in several platforms, a sys…
Tunable phononic coupling in excitonic quantum emitters
Adina Ripin, Ruoming Peng, Xiaowei Zhang +6
Engineering the coupling between fundamental quantum excitations is at the heart of quantum science and technologies. A significant case is the creation of quantum light sources in…
