Magnetic Hofstadter cascade in a twisted semiconductor homobilayer
Benjamin A. Foutty, Aidan P. Reddy, Carlos R. Kometter +4
Transition metal dichalcogenide moiré homobilayers have emerged as a platform in which magnetism, strong correlations, and topology are intertwined. In a large magnetic field, the…
Anomalous Landau level gaps near magnetic transitions in monolayer WSe
Benjamin A. Foutty, Vladimir Calvera, Zhaoyu Han +7
First-order phase transitions produce abrupt changes to the character of both ground and excited electronic states. Here we conduct electronic compressibility measurements to map t…
Harnessing excitons at the nanoscale -- photoelectrical platform for quantitative sensing and imaging
Zhurun Ji, Mark E. Barber, Ziyan Zhu +8
Excitons -- quasiparticles formed by the binding of an electron and a hole through electrostatic attraction -- hold promise in the fields of quantum light confinement and optoelect…
Mapping twist-tuned multiband topology in bilayer WSe
Benjamin A. Foutty, Carlos R. Kometter, Trithep Devakul +5
Semiconductor moiré superlattices have been shown to host a wide array of interaction-driven ground states. However, twisted homobilayers have been difficult to study in the limit…
Hofstadter states and reentrant charge order in a semiconductor moiré lattice
Carlos R. Kometter, Jiachen Yu, Trithep Devakul +7
The emergence of moiré materials with flat bands provides a platform to systematically investigate and precisely control correlated electronic phases. Here, we report local electro…
Tunable spin and valley excitations of correlated insulators in -valley moiré bands
Benjamin A. Foutty, Jiachen Yu, Trithep Devakul +6
Moiré superlattices formed from transition metal dichalcogenides (TMDs) have been shown to support a variety of quantum electronic phases that are highly tunable using applied elec…
Emergent Dirac gullies and gully-symmetry breaking quantum Hall states in ABA trilayer graphene
Alexander A. Zibrov, Rao Peng, Carlos Kometter +7
We report on quantum capacitance measurements of high quality, graphite- and hexagonal boron nitride encapsulated Bernal stacked trilayer graphene devices. At zero applied magnetic…
Even denominator fractional quantum Hall states at an isospin transition in monolayer graphene
A. A. Zibrov, E. M. Spanton, H. Zhou +4
Magnetic fields quench the kinetic energy of two dimensional electrons, confining them to highly degenerate Landau levels. In the absence of disorder, the ground state at partial L…
Robust fractional quantum Hall states and continuous quantum phase transitions in a half-filled bilayer graphene Landau level
Alexander A. Zibrov, Carlos. R. Kometter, Haoxin Zhou +5
Nonabelian anyons offer the prospect of storing quantum information in a topological qubit protected from decoherence, with the degree of protection determined by the energy gap se…
