When a Magnet Isn’t a Magnet

Using an application that took the 2009 Gordon Bell Prize as the world’s most advanced scientific computing application, a team led by ORNL’s Markus Eisenbach has been simulating the magnetic properties of promising materials, focusing in particular on the magnetocaloric effect. Its work is detailed in three recent papers in…

It Takes Three to Tango

The nucleus of an atom, like most everything else, is more complicated than we first thought. Just how much more complicated is the subject of a Petascale Early Science project led by ORNL’s David Dean.

Quantum Spin Doctors Dissect Exotic States of Matter

When German physicist Max Planck created quantum theory in 1900, he was not trying to revolutionize the world. He was just trying to provide a theoretical foundation for the way a heated object radiates energy and, thereby, to improve the efficiency of light bulbs. Modern scientists, too, cannot know which…
