Hybrid metal-semiconductor quantum dots in InAs as a platform for quantum simulation
Praveen Sriram, Connie L. Hsueh, Karna A. Morey +6
Arrays of hybrid metal-semiconductor islands offer a new approach to quantum simulation, with key advantages over arrays of conventional quantum dots. Because the metallic componen…
Extended Fractional Chern Insulators Near Half Flux in Twisted Bilayer Graphene Above the Magic Angle
Joe Finney, Aaron L. Sharpe, Linsey K. Rodenbach +7
Fractional Chern insulators (FCIs) -- the lattice analog of fractional quantum Hall states -- form as fractionalized quasiparticles emerge in a partially-filled Chern band. This fr…
Deterministic fabrication of graphene hexagonal boron nitride moiré superlattices
Rupini V. Kamat, Aaron L. Sharpe, Mihir Pendharkar +11
The electronic properties of moiré heterostructures depend sensitively on the relative orientation between layers of the stack. For example, near-magic-angle twisted bilayer graphe…
Measured potential profile in a quantum anomalous Hall system suggests bulk-dominated current flow
Ilan T. Rosen, Molly P. Andersen, Linsey K. Rodenbach +5
Ideally, quantum anomalous Hall systems should display zero longitudinal resistance. Yet in experimental quantum anomalous Hall systems elevated temperature can make the longitudin…
Bulk dissipation in the quantum anomalous Hall effect
Linsey K. Rodenbach, Ilan T. Rosen, Eli J. Fox +5
Even at the lowest accessible temperatures, measurements of the quantum anomalous Hall (QAH) effect have indicated the presence of parasitic dissipative conduction channels. There…
Absence of strong localization at low conductivity in the topological surface state of low disorder Sb2Te3
Ilan T. Rosen, Indra Yudhistira, Gargee Sharma +5
We present low-temperature transport measurements of a gate-tunable thin film topological insulator system that features high mobility and low carrier density. Upon gate tuning to…
