Fermiology and the Candidate Chiral Superconductor in Rhombohedral Tetralayer Graphene
Sandesh S. Kalantre, Ben H. Alexander, Julian May-Mann +11
Chiral superconductivity, in which the phase of the superconducting order parameter winds in momentum space, has long been sought for its close link to topological superconductivit…
Superconducting Dome in Ionic Liquid Gated Homoepitaxial Strontium Titanate Thin Films
Sushant Padhye, Jin Yue, Shivasheesh Varshney +3
In this work, we patterned a two-dimensional electron gas (2DEG) on the surface of a SrTiO thin film grown homoepitaxially on SrTiO by hybrid molecular beam epitaxy (hMBE).…
Directional ballistic magnetotransport in the delafossite metals PdCoO and PtCoO
Michal Moravec, Graham Baker, Maja D. Bachmann +9
Studies of electronic transport in width-restricted channels of PdCoO have recently revealed a novel `directional ballistic' regime, in which ballistic propagation of electrons…
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…
Automated Tabletop Exfoliation and Identification of Monolayer Graphene Flakes
Elijah D. S. Courtney, Mihir Pendharkar, Nathan J. Bittner +2
Over the past two decades, graphene has been intensively studied because of its remarkable mechanical, optical, and electronic properties. Initial studies were enabled by manual ``…
