Pressure and Proximity Tuned Twisted Bilayer Graphene
David T. S. Perkins, Joseph J. Betouras
The coupling between layered atomically-thin materials mediated by van der Waals forces allows strong electronic correlations, unique topological signatures, and non-trivial spin t…
Twisted Kagome Bilayers: High-Order Van Hove Singularities, Sublattice Interference, Magic Angles, and Possible Topology
David T. S. Perkins, Joseph J. Betouras
We develop a low-energy continuum model to describe the moiré physics of heterostructures, which is a generalization of the celebrated Bistritzer-MacDonald (BM) method [R. Bistritz…
Anisotropic scattering rates in strain-tuned SrRuO
Ben Currie, David T. S. Perkins, Evgeny Kozik +2
Motivated by recent angle-resolved photoemission spectroscopy (ARPES) experiments, we analyze the temperature, frequency, and momentum dependence of the single-particle scattering…
Designing Topological High-Order Van Hove Singularities: Twisted Bilayer Kagomé
David T. S. Perkins, Anirudh Chandrasekaran, Joseph J. Betouras
The interplay of high-order Van Hove singularities and topology plays a central role in determining the nature of the electronic correlations governing the phase of a system with u…
Symmetry Preservation in Commensurate Twisted Bilayers
David T. S. Perkins
Symmetry plays a key role in materials hosting Dirac electrons and underpins our ability to completely flatten the Dirac cone through the tuning of physical parameters such as twis…
