Ferroelectric-tunable quantum nonlinearity of chiral Bloch electrons in a moiré system
Zitian Pan, Jundong Zhu, Yu Hong +7
Sliding ferroelectricity in van der Waals materials shows great potential for designing robust memory devices. However, its thermodynamic behaviors and the coupling with certain qu…
Observation of Integer and Fractional Chern insulators in high Chern number flatbands
Jingwei Dong, Le Liu, Jundong Zhu +11
Moiré flatbands with high Chern numbers (C>1) offer opportunities to study the fractional quantum anomalous Hall effects that go beyond the Landau level paradigm with C=1, which r…
Electric field tunable coupling strength and quantum metric hot spots in a moiré flatband superconductor
Le Liu, Yu Hong, Chengping Zhang +9
Superconductivity in flatband systems has attracted tremendous attention in condensed matter physics. Alternating twisted multilayer graphene presents a compelling multiband system…
Observation of electrical high-harmonic generation
Xiaozhou Zan, Ming Gong, Zitian Pan +12
High-harmonic generation (HHG), an extreme nonlinear effect, introduces an unprecedented paradigm to detect emergent quantum phases and electron dynamics inconceivable in the frame…
