2020/6/19
A team of Brown University physicists has developed a new type of compact, ultra-sensitive magnetometer. The new device could be useful in applications involving weak magnetic fields, the re...
Fast-ignition design transport studies: realistic electron source, integrated PIC-hydrodynamics, imposed magnetic fields
Fast-ignition design transport realistic electron source integrated PIC-hydrodynamics imposed magnetic fields
2012/5/29
Transport modeling of idealized, cone-guided fast ignition targets indicates the severe challenge posed by fast-electron source divergence. The hybrid particle-in-cell [PIC] code Zuma is run in tandem...

Aggregation of superparamagnetic magnetic
2010/11/25
Experimental and simulation studies of superparamagnetic colloids in strong external fields have systematically shown an irreversible aggregation process in which chains of particles steadily grow and...
