Transport signatures of valley polarization in graphene multilayers: In-plane linear magnetoconductivity vs anomalous Hall effect
Fernando Peñaranda, Fernando de Juan
In two-dimensional materials where interacting Fermi pockets occur in valleys related by time-reversal symmetry, a spontaneous valley imbalance results in a novel state known as an…

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…

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…
