Best of Last Week: Living robots, the limits of universality, and switching to 1% milk
It was another good week for physics as a combined team from Rice University and Vienna University of Technology found billions of quantum entangled … n a "strange metal." The ytterbium, rhodium and silicon compound tests provided the strongest direct evidence to date of entanglement's role in bringing about quantum criticality. And a team with members from the National Institute of Standards and Technology and the University of Colorado Boulder tested the limits of universal … an ultracold system, and discovered Efimov trimers with sizes that were significantly larger than what the universal theory predicts. Also, an international team subjected a water sample to 20 times normal Earth gravity within ESA's Large Diameter Centrifuge and found the typical timescales of wave interactions and dissipation did not depend on the wave frequency, as predicted by theory.
