Quantum Phase Transitions and Fractional Quantized Anomalous Hall Insulators in Rhombohedral Graphene
Zach Hadjri, Xinlei Yue, Tonghang Han +10
Fractional quantum anomalous Hall effect (FQAHE) has been discovered in twisted MoTe and rhombohedral graphene/hBN moiré superlattices. Such van der Waals heterostructures feat…
Evidence of Metallic Wigner Crystal in Rhombohedral Graphene
Tonghang Han, Jackson P. Butler, Shenyong Ye +15
When the Coulomb interaction dominates over kinetic energy, electrons can crystallize into a Wigner crystal (WC). This paradigmatic correlated electronic phase has been realized in…
Family of Unconventional Superconductivities in Crystalline Graphene
Junseok Seo, Armel A. Cotten, Mingchi Xu +17
Unconventional superconductors exhibit multiple broken symmetries and exceed the range of the Bardeen-Cooper-Schrieffer (BCS) theory. For instance, time-reversal symmetry can be br…
On-Chip Terahertz Spectroscopy for Dual-Gated van der Waals Heterostructures at Cryogenic Temperatures
Junseok Seo, Zhengguang Lu, Seunghyun Park +10
Van der Waals heterostructures have emerged as a versatile platform to study correlated and topological electron physics. Spectroscopy experiments in the THz regime are crucial, si…
Extended Quantum Anomalous Hall States in Graphene/hBN Moiré Superlattices
Zhengguang Lu, Tonghang Han, Yuxuan Yao +7
Electrons in topological flat bands can form novel topological states driven by the correlation effects. The penta-layer rhombohedral graphene/hBN moire superlattice has been shown…
Signatures of Chiral Superconductivity in Rhombohedral Graphene
Tonghang Han, Zhengguang Lu, Zach Hadjri +20
Chiral superconductors are unconventional superconducting states that break time reversal symmetry spontaneously and typically feature Cooper pairing at non-zero angular momentum.…
