“It is such an honor for me,” Sjostrom said. “It is rewarding to see this field of theoretical research in warm dense matter, which has had many contributors in recent years and is an active research area, recognized by the award.”
Sjostrom has been involved in warm dense matter research for more than 10 years, with the goal of providing theoretical understanding and accurate characterization of materials in extreme conditions. Warm dense matter encompasses ionized fluids at the confluence of condensed matter physics, plasma physics, and dense liquids.
Sjostrom’s work toward broad-ranging quantum Monte Carlo calculations for the uniform electron gas earned him the John Dawson Award. These calculations provide the starting point to develop finite-temperature exchange-correlation functionals employed in density functional theory calculations.
“Travis’ work is crucial to mission challenges in weapons physics and simultaneously the frontiers of astrophysics. The recognition by the American Physical Society of his contributions is particularly gratifying,” said John Sarrao, deputy director for Science, Technology, and Engineering at Los Alamos National Laboratory.
The John Dawson Award was established by APS in 1981. According to APS, the award is given to scientists who make essential contributions to research achievements.
Los Alamos National Laboratory, a multidisciplinary research institution engaged in strategic science on behalf of national security, is managed by Triad, a public service oriented, national security science organization equally owned by its three founding members: Battelle Memorial Institute (Battelle), the Texas A&M University System (TAMUS), and the Regents of the University of California (UC) for the Department of Energy’s National Nuclear Security Administration.
Los Alamos enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
