Abstract:We introduce a novel two-dimensional dimerized lattice model that reveals a remarkable feature: the emergence of a complex, nontrivial topological multiferroic phase marked by zero Berry curvature and a significant Berry connection that influences the model's bulk topology. This model extends the one-dimensional Rice-Mele Hamiltonian model to explore polarization-dependent topological properties in a 2D Su-Schrieffer-Heeger lattice, providing a detailed framework for studying the impact of symmetry-breaking an… Show more
