Fractional Chern insulators in magic-angle twisted bilayer graphene
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +12
Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue toward manipulating non-abelian excitations. Early theoreti…
Unusual magnetotransport in twisted bilayer graphene
Joe Finney, Aaron L. Sharpe, Eli J. Fox +10
We present transport measurements of bilayer graphene with 1.38° interlayer twist and apparent additional alignment to its hexagonal boron nitride cladding. As with other devices w…
Unconventional sequence of correlated Chern insulators in magic-angle twisted bilayer graphene
Andrew T. Pierce, Yonglong Xie, Jeong Min Park +11
The interplay between strong electron-electron interactions and band topology can lead to novel electronic states that spontaneously break symmetries. The discovery of flat bands i…
Hyperbolic enhancement of photocurrent patterns in minimally twisted bilayer graphene
Sai S. Sunku, Dorri Halbertal, Tobias Stauber +10
Quasi-periodic moiré patterns and their effect on electronic properties of twisted bilayer graphene (TBG) have been intensely studied. At small twist angle , due to atomic recon…
Moiré metrology of energy landscapes in van der Waals heterostructures
Dorri Halbertal, Nathan R. Finney, Sai S. Sunku +20
The emerging field of twistronics, which harnesses the twist angle between two-dimensional materials, represents a promising route for the design of quantum materials, as the twist…
Electrically tunable correlated and topological states in twisted monolayer-bilayer graphene
Shaowen Chen, Minhao He, Ya-Hui Zhang +8
Twisted van der Waals heterostructures with flat electronic bands have recently emerged as a platform for realizing correlated and topological states with an extraordinary degree o…
High quality electrostatically defined hall bars in monolayer graphene
Rebeca Ribeiro-Palau, Shaowen Chen, Yihang Zeng +4
Realizing graphene's promise as an atomically thin and tunable platform for fundamental studies and future applications in quantum transport requires the ability to electrostatical…
Magic Angle Spectroscopy
Alexander Kerelsky, Leo McGilly, Dante M. Kennes +9
The electronic properties of heterostructures of atomically-thin van der Waals (vdW) crystals can be modified substantially by Moiré superlattice potentials arising from an interla…
Tuning superconductivity in twisted bilayer graphene
Matthew Yankowitz, Shaowen Chen, Hryhoriy Polshyn +5
Materials with flat electronic bands often exhibit exotic quantum phenomena owing to strong correlations. Remarkably, an isolated low-energy flat band can be induced in bilayer gra…
Competing Fractional Quantum Hall and Electron Solid Phases in Graphene
Shaowen Chen, Rebeca Ribeiro-Palau, Kang Yang +5
We report experimental observation of the reentrant integer quantum Hall effect in graphene, appearing in the N2 Landau level. Similar to high-mobility GaAs/AlGaAs heterostructu…
Electron optics with ballistic graphene junctions
Shaowen Chen, Zheng Han, Mirza M. Elahi +9
Electrons transmitted across a ballistic semiconductor junction undergo refraction, analogous to light rays across an optical boundary. A pn junction theoretically provides the equ…
Faraday rotation echo spectroscopy and detection of quantum fluctuations
Shao-Wen Chen, Ren-Bao Liu
Central spin decoherence is useful for detecting many-body physics in environments and moreover, the spin echo control can remove the effects of static thermal fluctuations so that…
Phase transitions in the complex plane of physical parameters
Bo-Bo Wei, Shao-Wen Chen, Hoi-Chun Po +1
At low temperature a thermodynamic system undergoes a phase transition when a physical parameter passes through a singularity point of the free energy, corresponding to formation o…
Quantum criticality at infinite temperature
Shao-Wen Chen, Ren-Bao Liu
Quantum criticality, being important as an indicator of new quantum matters emerging, is known to occur only at zero or low temperature. We find that a quantum probe, if its cohere…
