Quantum Geometric Bounds in Non-Hermitian Systems
Analysis
This paper investigates quantum geometric bounds in non-Hermitian systems, which are relevant to understanding real-world quantum systems. It provides unique bounds on various observables like geometric tensors and conductivity tensors, and connects these findings to topological systems and open quantum systems. This is significant because it bridges the gap between theoretical models and experimental observations, especially in scenarios beyond idealized closed-system descriptions.
Key Takeaways
- •Identifies quantum geometric bounds for observables in non-Hermitian systems.
- •Provides unique bounds on non-Hermitian quantum geometric tensors, generalized two-point response correlators, conductivity tensors, and optical weights.
- •Connects findings to topological systems with non-Hermitian Chern numbers.
- •Demonstrates relevance to open quantum systems governed by Lindbladian dynamics.
- •Addresses experimental observables and responses beyond idealized closed-system descriptions.
