World's first 3-D Simulations of Superluminous Supernovae
For the first time ever, an international team of astrophysicists simulated the three-dimensional (3-D) physics of superluminous supernovae — which are about a hundred times more luminous than typical supernovae. They achieved this milestone using Berkeley Lab's CASTRO code and supercomputers at NERSC. Read More »
Designing Materials with Tunable Electrical and Magnetic Behaviors
For the first time, the coupling of magnetic spins and atomic dynamics has been fully described in hexagonal iron sulfide (h-FeS), explaining the origin of its fascinating coexistence of metal-insulator, structural, and magnetic transitions. Read More »
New Conservation Laws in Turbulent Magnetized Flows
University of Rochester (UofR) researchers used a novel coarse-graining framework for disentangling multiscale interactions to find the existence of two separate conservation laws over an entire range of length scales in turbulent magnetized flows. The work relied on a suite of massively parallel simulations run on NERSC using the DiNuSUR code developed at UofR. Read More »
Petawatt Laser Guiding and Electron Beam Acceleration to 8 GeV in a Laser-Heated Capillary Discharge Waveguide
Researchers at Berkeley Lab’s BELLA Center set a new world record in laser-driven plasma-based electron acceleration by obtaining beams with an energy of up to 7.8 GeV in a 20 cm-long plasma using the high-power BELLA laser. The maximum achieved energy nearly doubled their previous record set in 2014. Read More »
Machine-Learned Impurity Level Prediction in Semiconductors
Argonne National Laboratory (ANL) researchers ran high-throughout atomistic simulations on NERSC supercomputers and generated comprehensive computational datasets of impurity properties in two classes of semiconductors: lead-based hybrid perovskites and Cd-based chalcogenides. These datasets led to machine learned models which enable accelerated prediction and design for the entire chemical space of materials and impurities in these semiconductor class. Read More »
