Abstract

Topological band theory based on the variety of reciprocal space invariants provides an insightful framework for quantum material characterization in condensed matter physics. Its bulk-boundary correspondence principle has become a reliable tool for predicting Fermi level properties. Here we investigate a recently proposed bottom-up topological engineering based on reciprocal space invariants and show its connection to a real space <i>in situ</i> topology of a Kekulé structure originating in organic chemistry. We show that these approaches can be effectively used to engineer magnetic-field-free tunable chiral anomalies that are promising for energy-efficient electronic transport.
