Quantum squeeze wrings uncertainty from atom waves

Article Abstract:

Roberto Merlin et al have succeeded in squeezing the quantum fluctuation in phonons, the wavelike vibrations of atoms in solids. Ultrafast laser pulses knock atoms in potassium tantalate out of their normal frequency, squeezing randomness out at one point in exchange for increased chaos elsewhere.

The looming neutron gap

Article Abstract:

The loss of funding for the $2.8 billion Advanced Neutron Source is a serious setback for neutron scattering researchers. Both US and European researchers face a lack of access to neutron sources. The Clinton administration is backing construction of a spallation source.
