In recent years, it has been shown that Berry curvature monopoles and dipoles play
essential roles in the anomalous Hall and the nonlinear Hall effects, respectively. In this …

Twisted bilayer graphene is highly sensitive to external perturbations. Strains, and the
presence of the substrate, break the symmetries of the central bands. The resulting changes …

We propose a systematic analysis method for identifying essential parameters in various
linear and nonlinear response tensors without which they vanish. By using the Keldysh …
