Rashba spin-orbit coupled systems are an important class of materials notedfor diverse fundamental and applied phenomena. Recently, the emergence ofnon-linear Hall effect under conditions of time-reversal symmetry has beendiscovered in materials with broken inversion symmetry. In this work, we studythe second- and third-order Hall response in Rashba systems with hexagonalwarping. Starting with a low-energy model, we obtain the analytic expressionsand discover the unique dipole profile in Rashba systems with hexagonalwarping. Furthermore, we extend the analysis using a realistic tight-bindingmodel. Next, we predict the existence of a third-order Hall effect in thesesystems, and calculate the Berry connection polarizability tensor analytically.We also show how the model parameters affect the third-order conductivity. Ourpredictions can help in the experimental realization of Berry curvaturemultipole physics in Rashba materials with hexagonal warping, and provide a newplatform for engineering the non-linear Hall effects.
