Sizing up the scales

September, 2013 Updated: September, 2013

Exploring the breaking and rejoining of magnetic-field lines requires simulations and computation. A simulation’s accuracy, however, depends on various issues of scale. Magnetic reconnection’s multiscale nature exacerbates the challenge of simulating it. Early research was based entirely on fluid models in just two dimensions, since kinetic simulations were infeasible. Kinetic modeling requires the space and […]

Predicting solar assaults

September, 2013 Updated: September, 2013

When Earth’s magnetosphere snaps and crackles, power and communications technologies can break badly. Three-dimensional simulations of magnetic reconnection aim to forecast the space storms that disrupt and damage.

Pounding out atomic nuclei

March, 2011 Updated: November, 2011

Thousands of tiny systems called atomic nuclei – specific combinations of protons and neutrons – prove extremely difficult to study but have big implications for nuclear stockpile stewardship. To describe all of the nuclei and the reactions between them, a nationwide collaboration is devising powerful algorithms that run on high-performance computers.

Cranking up the speed of DFT

March, 2011 Updated: March, 2011

Density functional theory (DFT) can be used to determine densities of protons and neutrons making up a nucleus. “If we can determine those densities precisely,” says Witold Nazarewicz, professor of physics at the University of Tennessee, “we can determine the binding energy – the energy stored in the nucleus.” The energy density functional (EDF) in […]
