Search and Discovery Hysteresis steps demonstrate quantum tunneling of molecular spins. When molecular spins in a crystal tunnel in lockstep under potential barriers, one sees not only a spectacular demonstration of quantum effects, but also the promise of magnetic information storage by individual molecules.
Experiment signals a new phase of quantum dot measurements.
A sophisticated experiment has measured the phase change in the electronic wavefunction as a charge crosses a quantum dot, a tiny, nearly isolated bit of conducting material. The phase change gives new information about the electronic interactions, previously studied only through measurements of the magnitude of the transmission.
