The Haldane Model is a theoretical framework that describes a system of spinless fermions in a two-dimensional lattice, revealing unique properties related to topological phases of matter. It introduced the concept of topological insulators, which are materials that conduct electricity on their surfaces while remaining insulating in their bulk, showcasing robust edge states that arise from their non-trivial topology. This model has significantly impacted our understanding of quantum Hall effects and has applications in various fields such as condensed matter physics and materials science.
congrats on reading the definition of Haldane Model. now let's actually learn it.
