Occupation Dynamics of Floquet-Volkov States and Spectral Sum Rule
Xuanxi Cai, Changhua Bao, Benshu Fan +9
Time-periodic light fields can dress electronic states in quantum materials, forming Floquet states whose dynamic occupation determines transient material properties. Here by using…
Floquet optical selection rules in black phosphorus
Benshu Fan, Umberto De Giovannini, Hannes Hübener +4
Optical selection rules endorsed by symmetry are crucial for understanding the optical properties of quantum materials and the associated ultrafast spectral phenomena. Here, we int…
Two-Terminal Electrical Detection of the Néel Vector via Longitudinal Antiferromagnetic Nonreciprocal Transport
Guozhi Long, Hui Zeng, Mingxiang Pan +2
We propose a robust two-terminal electrical readout scheme for detecting the Néel vector orientation in antiferromagnetic (AFM) materials by leveraging longitudinal nonreciprocal…
Giant Rashba splitting in PtTe/PtTe heterostructure
Runfa Feng, Yang Zhang, Jiaheng Li +11
Achieving a large spin splitting is highly desirable for spintronic devices, which often requires breaking of the inversion symmetry. However, many atomically thin films are centro…
Moiré enhanced flat band in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Kai Liu +17
The fractional quantum anomalous Hall effect (FQAHE) is a fascinating emergent quantum state characterized by fractionally charged excitations in the absence of magnetic field,whic…
Imaging moiré flat bands and Wigner molecular crystals in twisted bilayer MoTe2
Yufeng Liu, Yu Gu, Ting Bao +16
Two-dimensional semiconducting moiré materials have emerged as a highly tunable platform for exploring novel quantum phenomena. Recently, tMoTe2 has attracted significant attentio…
