Division Staff in the News

Chris Fontes of XCP-5 has been named as a Fellow of the American Physical Society. He was nominated in the Division of Atomic, Molecular & Optical Physics, for his pioneering contributions to our understanding of atomic processes in plasmas and their application to a broad range of physics problems including nuclear fusion, laboratory experiment and astrophysics. 

The work of Jesse Canfield (XCP-4) on computational modeling of forest fires is being featured in the July issue of Popular Science.

Publications

Charlie Starrett (XCP-5) describes a new advancement in orbital-free molecular dynamics in a recent issue of Physical Review E. Read all about "Thomas-Fermi simulations of dense plasmas without pseudopotentials" at https://journals.aps.org/pre/abstract/10.1103/PhysRevE.96.013206
