Paper by Szalewicz group paves the way for greater precision in pressure measurement

May 1, 2015 - Most of us know helium as the lighter-than-air gas that puts lift into birthday balloons or makes a baritone's resonant voice sound more like Donald Duck's. But helium -- a non-toxic element that is abundant in the universe but a scarce, non-renewable resource on earth -- has many significant uses in industry, medicine and science.

Matthaeus and Shay to witness long-awaited launch of NASA research mission

March 11, 2015 - Don't even try to guess what NASA's next launch will deliver in technological advance, scientific understanding, and new research possibilities. That is mission impossible, says University of Delaware physicist William Matthaeus. "There is no way to predict what the impact will be," he said.

No one has ever seen what scientists expect to see in the $850 million Magnetospheric Multiscale mission, after all. And no one can imagine what the world will be like two years from now -- or 10 years.

Extreme data science approach to nonequilibrium quantum many-body systems: A synergy between physics, computer science and applied math

December 9, 2014 - In the recent review article published in International Journal of Modern Physics B, Prof. Nikolic and collaborators - Prof. Freericks from Physics and Prof. Frieder from Computer Science Departments at Georgetown University - have proposed new routes to tackle the challenge posed by quantum many-body systems far from equilibrium encountered in  condensed matter physics, AMO physics, plasma physics and cosmology.

Evidence for a common physical origin of the Landau and BEC theories of superfluidity

November 20, 2014 - In a recent Physical Review Letter article, which is highlighted by PRL as an “Editors Suggestion” to read, Prof. Mulders, Prof. Glyde and collaborators combine neutron scattering and torsional oscillator measurements to show that two originally quite separate theories of superfluidity in liquid 4He are based on mutually consistent liquid properties (phonons and BEC) that have a common physical origin.
