Moiré-mediated phases in synthetic Kondo superlattices [PDF]

Motivated by the recent experiments on van der Waals heterostructures involving metallic and Mott insulating layers, we construct a moiré extension of the Kondo-Heisenberg model and study its phase diagram via Abrikosov fermion mean field theory in one ...

Gate-dependent pseudospin mixing in graphene/boron nitride moiré superlattices

, 2014
Electrons in graphene are described by relativistic Dirac–Weyl spinors with a two-component pseudospin1–12. The unique pseudospin structure of Dirac electrons leads to emerging phenomena such as the massless Dirac cone2, anomalous quantum Hall eect2,3 ...
