Overview

This study identifies conditions for bulk-edge correspondence in topological insulators, suggesting implications for edge states.

Key Points

  • Anomalous behavior can occur in bulk-edge correspondence under varying boundary conditions, leading to unexpected violations.
  • K-theoretic conditions are established to link unbounded Hamiltonians to observable algebras, aiding in clearer characterizations.
  • The study provides a systematic approach to understanding boundary-induced corrections in topological phases.
  • This work reveals how von Neumann unitaries contribute to the number of protected edge states in varied boundary scenarios.
