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…
