Author(s): Akash Dey We investigate the nonlinear Hall responses in tunable two-dimensional Dirac materials. In particular, we study quantum geometry-driven second and third-order nonlinear responses in a time-reversal symmetric Dirac semimetal that can host a single-node, a double-node, and a nodal-ring depending on th… [Phys.
