Ultrafast Charge-Doping via Photo-Thermionic Injection in van der Waals Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Van der Waals (vdW) heterostructures of two-dimensional (2D) materials have become a rich playground for the exploration of correlated quantum phases, and recent studies have begun…
Photoinduced Metal-to-Insulator Transitions in 2D Moiré Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Photoexcitation has been utilized to control quantum matter and to uncover metastable phases far from equilibrium. Among demonstrations to date, the most common is the photo-induce…
Rydberg Exciton Dynamics in the Blockade Regime of Cu2O
Gillian E. Minarik, Eric A. Arsenault, Vinícius da Silveira Lan Avelar +2
Hosting giant Rydberg excitons with principal quantum numbers up to n = 30, cuprous oxide (Cu2O) provides a rare solid-state setting for exploring Rydberg physics, as exemplified b…
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…
Observation of Coherent Ferron Emission and Propagation
Jeongheon Choe, Taketo Handa, Chun-Ying Huang +16
Excitation of ordered quantum phases gives rise to collective modes and quasiparticles, as exemplified by spin waves and magnons emerging from magnetic order. Extending this paradi…
