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…
Frustrated hopping from orbital decoration of a primitive two-dimensional lattice
Aravind Devarakonda, Christie S. Koay, Daniel G. Chica +18
Materials hosting flat electronic bands are a central focus of condensed matter physics as promising venues for novel electronic ground states. Two-dimensional (2D) geometrically f…
Electronic interactions in Dirac fluids visualized by nano-terahertz spacetime interference of electron-photon quasiparticles
Suheng Xu, Yutao Li, Rocco A. Vitalone +15
Ultraclean graphene at charge neutrality hosts a quantum critical Dirac fluid of interacting electrons and holes. Interactions profoundly affect the charge dynamics of graphene, wh…
Time-Domain Signatures of Distinct Correlated Insulators in a Moiré Superlattice
Eric A. Arsenault, Yiliu Li, Birui Yang +6
Among expanding discoveries of quantum phases in moiré superlattices, correlated insulators stand out as both the most stable and most commonly observed. Despite the central impor…
Low-Energy Electronic Structure in the Unconventional Charge-Ordered State of ScVSn
Asish K. Kundu, Xiong Huang, Eric Seewald +15
Kagome vanadates {\it A}VSb display unusual low-temperature electronic properties including charge density waves (CDW), whose microscopic origin remains unsettled. Recently…
