"Unraveling Eternal Stability: The Quantum Trick's Downfall"
Originally Published 1 year ago — by Quanta Magazine
Physicists have been debating the stability of a quantum phenomenon known as many-body localization (MBL) in one-dimensional chains. Recent research has challenged the long-held belief in the eternal stability of MBL, with the discovery of a new thermalization-causing phenomenon called avalanches. These findings have led to a reevaluation of the MBL phase diagram, suggesting that MBL may not be as stable as previously thought. The debate revolves around a mathematical proof of MBL's existence, with researchers working to either contradict or verify it. While the stability of MBL remains uncertain, physicists are excited about the opportunity to discover new phenomena in quantum systems.
