Flatland physics probes mysteries of superfluidity

If physicists lived in Flatland—the fictional two-dimensional world invented by Edwin Abbott in his 1884 novel—some of their quantum physics experiments would turn out differently (not just thinner) than those in our world.

Superfluid-superconductor relationship is detailed

Scientists have studied superconductors and superfluids for decades. Now, researchers at Washington University in St. Louis have drawn the first detailed picture of the way a superfluid influences the behavior of a superconductor. In addition to describing previously unknown superconductor behavior, these calculations could change scientists' understanding of the motion of neutron stars.

Strange fluids may shed light on universe

IT’S an ambitious task, recreating the universe in a bucket. But if it is successful, the experiment could help solve the twin puzzles of why we’re made of matter rather than antimatter and where the huge magnetic fields that span galaxies come from.

Researchers create new form of matter

Physicists at the University of Pittsburgh have demonstrated a new form of matter that melds the characteristics of lasers with those of the world's best electrical conductors. The work introduces a new method of moving energy from one point to another as well as a low-energy means of producing a light beam like that from a laser. The Pitt researchers and their collaborators at the Bell Labs of Alcatel-Lucent in New Jersey detail the process in the May 18 issue of the journal Science.

New model describes avalanche behavior of superfluid helium

By utilizing ideas developed in disparate fields, from earthquake dynamics to random-field magnets, researchers at the University of Illinois have constructed a model that describes the avalanche-like, phase-slip cascades in the superflow of helium.
