United KingdomResearchers have discovered a new class of quantum oscillation related to the nonlinear Hall effect in twisted double bilayer graphene. The study, published in Physical Review Letters, explores how the second-order nonlinear Hall effect arises in two-dimensional materials lacking inversion symmetry. This phenomenon is connected to the Berry curvature, a geometric property influencing electron wave functions.
