Quantum Theory Seminar - Amit Goft (Techion)

Friday, March 15, 2024 at 3:30pm to 4:30pm

Clark , 701 142 Sciences Drive

Title: Building Topological Materials from Thermodynamic Topological

Defects Topological defects in thermodynamic phases are characterized by winding numbers of order parameters. Similarly, topological phases in the tenfold classification of insulators and superconductors are characterized by Chern and winding numbers. We show that both situations can be described by a single formalism, using the notion of the symbol of a Hamiltonian which contains all relevant topological information. The symbol generalizes Bloch Hamiltonians and order parameters. Vacancies in graphene offer a useful example.

Faculty Hosts: Eun-Ah Kim, Chao-Ming Jian, and Debanjan Chowdhury
