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
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.
Quantum gold
Driven by what’s missing in experiments, Brookhaven’s Yan Li applies quantum mechanics to compute the physical properties of materials.
