We propose a nonlinear dynamical Hall effect characteristic of layered materials with chiral symmetry, which is driven by the joint action of in-plane and time variation of out-of-plane ac fields jH∼Ė⊥×E∥. A different band geometric quantity—interlayer Berry connection polarizability, which probes a mixed quantum metric characteristic of layer hybridized electrons by twisted interlayer coupling—underlies this effect.

Correction to: Nature Communications https://doi.org/10.1038/s41467-023-37644-0, published online 07 April 2023The original PDF version of this Article contained an error in the expression for the k-space vorticity of the layer current on the second line below Equation 6, where a partial derivative was missing as the first term after the opening of the square bracket. This has been corrected in the PDF version of the Article.

AbstractUnder time-reversal symmetry, a linear charge Hall response is usually deemed to be forbidden by the Onsager relation. In this work, we discover a scenario for realizing a time-reversal even linear charge Hall effect in a non-isolated two-dimensional crystal allowed by time reversal symmetry. The restriction by Onsager relation is lifted by interfacial coupling with an adjacent layer, where the overall chiral symmetry requirement is fulfilled by a twisted stacking.
