Magnetic injection photocurrents in valley polarized states of twisted bilayer graphene
Fernando Peñaranda, Héctor Ochoa, Fernando de Juan
Magic-angle twisted bilayer graphene displays a complex phase diagram as a function of flat band filling, featuring compressibility cascade transitions and a variety of competing g…
Temperature crossovers in the specific heat of amorphous magnets
Hector Ochoa
It is argued that the specific heat of amorphous solids at low temperatures can be understood to arise from a single branch of collective modes. The idea is illustrated in a model…
Flat and tunable moire phonons in twisted transition-metal dichalcogenides
Alejandro Ramos-Alonso, Benjamin Remez, Daniel Bennett +2
Displacement fields are one of the main tuning knobs employed to engineer flat electronic band dispersions in twisted van der Waals multilayers. Here, we show that electric fields…
Intrinsic and extrinsic photogalvanic effects in twisted bilayer graphene
Fernando Peñaranda, Hector Ochoa, Fernando de Juan
The chiral lattice structure of twisted bilayer graphene with D6 symmetry allows for intrinsic photogalvanic effects only at off-normal incidence, while additional extrinsic effect…
