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…
Field-induced asymmetric band flattening and ideal quantum geometry in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Size Wu +17
Rhombohedral graphene exhibits an exceptionally diverse array of correlated phases that depend sensitively on the displacement field. Compiling reported phases into a unified phase…
Observation of Floquet-induced gap in graphene
Fei Wang, Xuanxi Cai, Xiao Tang +8
Floquet engineering provides a powerful pathway for creating non-equilibrium phases of matter with tailored electronic structures and properties through time-periodic driving. As t…
Structural and electronic signatures of strain-tunable marginally twisted bilayer graphene
Pei Ouyang, Jiawei Yu, Qian Li +11
Marginally twisted bilayer graphene having small twist angles is predicted to exhibit unique structural and electronic properties, though experimental characterization remains limi…
Moiré-modulated valley in twisted bilayer and twisted double-bilayer MoTe
Wanying Chen, Hongyun Zhang, Jinxi Lu +18
Twisted MoTe hosts intriguing correlated quantum phenomena including the fractional quantum anomalous Hall effect in twisted bilayer (t-BL) MoTe near 3.7, which is…
Strain and twist angle driven electronic structure evolution in twisted bilayer graphene
Jiawei Yu, Guihao Jia, Qian Li +14
In twisted bilayer graphene (TBG) devices, local strains frequently coexist and intertwine with the twist-angle-dependent moiré superlattice, significantly influencing the electro…
