Boundary Modes in Fracton Models - Workshop on Strong Electron Correlations

Explore boundary modes in fracton models through this 39-minute conference talk from the Workshop on Strong Electron Correlations in Quantum Materials. Delve into gapped edges of topological phases, Z2 topological order, and fracton "topological" order. Examine bulk properties, single defects, and the Chamon model with a boundary. Investigate effective field theory, boundary conditions, and methods to gap out boundary modes. Analyze correlations at weak coupling fixed points and the strong coupling regime. Gain insights into quantum materials, inhomogeneities, frustration, and topology from speaker Rodrigo Pereira of IIP & UFRN, Brazil.
