Article Synopsis
- Square-root topology is a new area in topological insulators that connects systems through squaring Hamiltonians, with extensions leading to higher-root versions that involve multiple squaring operations.*
-
- This research develops a framework for general n-root topological insulators using the Su-Schrieffer-Heeger model, employing non-Hermitian models with generalized chiral symmetry and unique edge states in a complex energy spectrum.*
-
- The study explores practical applications in photonic ring systems, where manipulated couplings can create high imaginary gauge fields, allowing for experimental validation of these new high-root topological models.*
