Classifying Fragile Topology Using Matrix Homotopy

Research output: Contribution to journalConference articlepeer-review

Abstract

We develop a Z2 energy-resolved topological marker for classifying fragile phases using a system's position-space description, enabling the direct classification of finite, disordered, and aperiodic materials, and illustrate this marker’s application in both material and photonic crystal systems.
