Single anyons and anyon binding in a quantum Hall dot
Marco Valentini, Will Wang, Amir Shapour Mohammadi +10
Anyons are particles with quantized fractional statistics. In theory, a single anyon can be stabilized as a localized fractional charge within the bulk of a topologically ordered t…
3D microwave imaging of a van der Waals heterostructure
Leonard W. Cao, Chen Wu, Lingyuan Lyu +9
Van der Waals (vdW) heterostructures offer a tunable platform for the realization of emergent phenomena in layered electron systems. While scanning probe microscopy techniques have…
Nanoscale infrared and microwave imaging of stacking faults in multilayer graphene
Ludwig Holleis, Liam Cohen, Noah Samuelson +14
Graphite occurs in a range of metastable stacking orders characterized by both the number and direction of shifts between adjacent layers by the length of a single carbon-carbon bo…
Slow quasiparticle dynamics and anyonic statistics in a fractional quantum Hall Fabry-Pérot interferometer
Noah L. Samuelson, Liam A. Cohen, Will Wang +5
Anyons are particles with fractional exchange statistics that emerge as elementary excitations of fractional quantum Hall phases. Experimentally, their exchange statistics can be m…
Spontaneous localization at a potential saddle point from edge state reconstruction in a quantum Hall point contact
Liam A. Cohen, Noah L. Samuelson, Taige Wang +7
Quantum point contacts (QPCs) are an essential component in mesoscopic devices. Here, we study the transmission of quantum Hall edge modes through a gate-defined QPC in monolayer g…
Universal chiral Luttinger liquid behavior in a graphene fractional quantum Hall point contact
Liam A. Cohen, Noah L. Samuelson, Taige Wang +4
One dimensional conductors are described by Luttinger liquid theory, which predicts a power-law suppression of the density of states near the Fermi level. The scaling exponent is n…
Nanoscale electrostatic control in ultra clean van der Waals heterostructures by local anodic oxidation of graphite gates
Liam A. Cohen, Noah L. Samuelson, Taige Wang +7
In an all-van der Waals heterostructure, the active layer, gate dielectrics and gate electrodes are assembled from two-dimensional crystals that have a low density of atomic defect…
