Forget solid, liquid, and gas: there are in fact more than 500 phases of matter. In a major paper in today's issue of Science, Perimeter Faculty member Xiao-Gang Wen reveals a modern reclassification of all of them. Condensed matter physics — the branch of physics responsible for discovering and describing most of these phases — has traditionally classified phases by the way their fundamental building blocks — usually atoms — are arranged. The key is something...

While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theoretical physicists at the Kavli Institute for Theoretical Physics (KITP) cover the range of questions in physics. Recently, theoretical physicists at KITP have made important strides in studying a concept in quantum physics called quantum entanglement, in...

Exotic Quantum States: A New Research Approach
2011-10-03 09:23:13

Theoretical physicists of the University of Innsbruck have formulated a new concept to engineer exotic, so-called topological states of matter in quantum mechanical many-body systems. They linked concepts of quantum optics and condensed matter physics and show a direction to build a quantum computer which is immune against perturbations. The scientists have published their work in the journal Nature Physics. Three years ago a research team led by Sebastian Diehl and Peter Zoller presented...


Word of the Day
grass-comber
  • A landsman who is making his first voyage at sea; a novice who enters naval service from rural life.
According to the OED, a grass-comber is also 'a sailor's term for one who has been a farm-labourer.'
