Explore advanced connections between lattice models and topological quantum field theories in this 53-minute conference talk from Harvard CMSA's Workshop on Quantum Field Theory and Topological Phases via Homotopy Theory and Operator Algebras. Delve into sophisticated mathematical frameworks that bridge discrete lattice systems with continuous field theoretical descriptions, examining how topological invariants emerge from quantum many-body systems. Investigate the interplay between homotopy theory and operator algebras in characterizing topological phases of matter, with particular emphasis on how lattice constructions can realize abstract topological quantum field theories. Analyze the mathematical structures underlying gapped quantum phases and their classification through algebraic topology, while understanding how these theoretical tools provide insights into condensed matter physics and quantum computation applications.
