Extended linear-in- resistivity due to electron-phason scattering in moiré superlattices
Héctor Ochoa, Rafael M. Fernandes
Due to its incommensurate nature, moiré superlattices host not only acoustic phonons but also another type of soft collective modes called phasons. Here, we investigate the impact…
Electric backaction on moiré mechanics
Héctor Ochoa
A lattice mismatch between Van der Waals layers produces a moiré pattern and a subsequent electron band reconstruction. When the bilayer is charged, the sliding motion of one layer…
Degradation of phonons in disordered moiré superlattices
Héctor Ochoa, Rafael M. Fernandes
The elastic collective modes of a moiré superlattice arise not from vibrations of a rigid crystal but from the relative displacement between the constituent layers. Despite their s…
Self-induced spin-orbit torques in metallic ferromagnets
Hector Ochoa, Ricardo Zarzuela, Yaroslav Tserkovnyak
We present a phenomenological theory of spin-orbit torques in a metallic ferromagnet with spin-relaxing boundaries. The model is rooted in the coupled diffusion of charge and spin…
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…
