Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO
Maja D. Bachmann, Aaron L. Sharpe, Arthur W. Barnard +6
Geometric electron optics may be implemented in solid state when transport is ballistic on the length scale of a device. Currently, this is realized mainly in 2D materials characte…

Emergent ferromagnetism near three-quarters filling in twisted bilayer graphene
Aaron L. Sharpe, Eli J. Fox, Arthur W. Barnard +5
When two sheets of graphene are stacked at a small twist angle, the resulting flat superlattice minibands are expected to strongly enhance electron-electron interactions. Here we p…
