Entanglement Dynamics in Non-Hermitian Topological Systems
Analysis
This paper investigates the interplay of topology and non-Hermiticity in quantum systems, focusing on how these properties influence entanglement dynamics. It's significant because it provides a framework for understanding and controlling entanglement evolution, which is crucial for quantum information processing. The use of both theoretical analysis and experimental validation (acoustic analog platform) strengthens the findings and offers a programmable approach to manipulate entanglement and transport.
Key Takeaways
- •Identifies three dynamic phases (bulk-like, edge-like, and skin-like) in non-Hermitian topological systems.
- •Entanglement entropy (EE) and transport currents are used as dynamic probes to distinguish these phases.
- •Skin-like dynamics show periodic information shuttling and oscillatory EE.
- •Edge-like dynamics lead to complete EE suppression.
- •Provides a programmable approach to steering entanglement and transport via tailored non-Hermitian couplings.
