Watching an object go quantum
Abstract:
Build a pendulum small enough, and it will violate Newton's classical laws of mechanics, following quantum rules instead. Some researchers hope to observe such violations by cooling a tiny wobbling object to very low temperatures. A team of theorists has now analyzed a vibrating bar, both classically and quantum mechanically, and predicted the signatures of quantum behavior that experimenters might observe, as they report in the 27 July Physical Review Letters ("Signatures for a Classical to Quantum Transition of a Driven Nonlinear Nanomechanical Resonator"). What's more, the team found that such a classical-to-quantum transition is within reach of current technology. They hope that experiments on small moving objects will soon shed light on a deep question: why do large objects obey classical laws?
