Universal moiré nematic phase in twisted graphitic systems
Carmen Rubio-Verdú, Simon Turkel, Larry Song +12
Graphene moiré superlattices display electronic flat bands. At integer fillings of these flat bands, energy gaps due to strong electron-electron interactions are generally observed…
Nonlinear twistoptics at symmetry-broken interfaces
Kaiyuan Yao, Nathan R. Finney, Jin Zhang +17
Broken symmetries induce strong nonlinear optical responses in materials and at interfaces. Twist angle can give complete control over the presence or lack of inversion symmetry at…
Strain-induced excitonic instability in twisted bilayer graphene
Hector Ochoa
The low-energy bands of twisted bilayer graphene form Dirac cones with approximate electron-hole symmetry at small rotation angles. These crossings are protected by the emergent sy…
Flat bands and chiral optical response of moiré insulators
H. Ochoa, A. Asenjo-Garcia
We present a low-energy model describing the reconstruction of the electronic spectrum in twisted bilayers of honeycomb crystals with broken sublattice symmetry. The resulting moir…
