25 4 Full Breakdown

Summary

Story summary

Researchers observed a long-lived prethermal state in a spin model with thousands of components that is influenced by local symmetries.
The prethermal state is stabilized by two-body interactions.
Defects cause decay by forming bubble-like structures in a false vacuum.
The breakdown follows the Kardar-Parisi-Zhang universality class.
The model can be realized with large-scale arrays of Rydberg atoms.

History

Historical Context

The Kardar-Parisi-Zhang (KPZ) equation, introduced in 1986 by Mehran Kardar, Giorgio Parisi, and Yi-Cheng Zhang, revolutionized the understanding of growth processes in statistical physics. This non-linear equation has since influenced various fields, including condensed matter and cosmology, and recent research on prethermal states continues to build on its insights, potentially advancing quantum computing and materials science.
