Non-Hermiticity Enhances Quantum Revivals in Lattice Gauge Theory

Published:Dec 30, 2025 19:00

•

1 min read

•

ArXiv

Analysis

This paper investigates the impact of non-Hermiticity on the PXP model, a U(1) lattice gauge theory. Contrary to expectations, the introduction of non-Hermiticity, specifically by differing spin-flip rates, enhances quantum revivals (oscillations) rather than suppressing them. This is a significant finding because it challenges the intuitive understanding of how non-Hermitian effects influence coherent phenomena in quantum systems and provides a new perspective on the stability of dynamically non-trivial modes.

Key Takeaways

•Non-Hermiticity, introduced through asymmetric spin-flip rates, can enhance quantum revivals in the PXP model.
•This enhancement is counterintuitive, as non-Hermiticity is often associated with decoherence.
•The effect can be understood through a similarity transformation mapping the non-Hermitian model to the standard PXP model.
•The work provides an analytically tractable example of how non-Hermiticity can stabilize coherent many-body modes.

Reference

“The oscillations are instead *enhanced*, decaying much slower than in the PXP limit.”
