Stirring by Staring: Measurement-Induced Chirality
Matthew Wampler, Brian J. J. Khor, Gil Refael, Israel Klich
Abstract
In quantum mechanics, the observer necessarily plays an active role in the dynamics of the system, making it difficult to probe a system without disturbing it. Here, we show that this apparent difficulty may be turned into a tool for driving an initially trivial system into a desired quantum many-body state simply by observing it.
