Second harmonic Hall responses of insulators as a probe of Berry curvature dipole
Berry curvature is the key component underlying various band geometric characteristics of solid state systems. Here, the authors investigate second-order susceptibility using perturbation theories and time-dependent simulations showing that the transverse optical response in insulators is governed b...

| Summary: | Berry curvature is the key component underlying various band geometric characteristics of solid state systems. Here, the authors investigate second-order susceptibility using perturbation theories and time-dependent simulations showing that the transverse optical response in insulators is governed by an interband Berry curvature dipole. |
