This means we need to understand how matter behaves when it is very hot (10,000 to 100,000,000 K) and at high density (1 to 1,000,000 g\/cm3). In this regime, atoms are partially ionized and significantly overlap, meaning that the usual low-density plasma physics methods are inaccurate. In our research group at Los Alamos National Laboratory, we have developed methods to accurately model these plasmas. In this talk I will review the progress we have made and some of the major outstanding challenges in this rapidly developing field.\n\nAbout the Speaker: \nDr. Charles Starrett received his PhD from the Queen\u2019s University of Belfast in 2007, where he worked on positronium collisions with matter. He went from there to a postdoctoral position at the French Alternative Energies and Atomic Energy Commission (CEA), where he began to study the structure of matter in warm and hot dense plasmas. In 2010 he joined Los Alamos National Laboratory to continue this work and still works in this field today. He has developed models to predict material properties such as equation of state, particle transport and opacity for applications ranging from fusion to astrophysics.\n\nThe seminar will be conducted in person, with livestream on Zoom.
