This event is the 12th in a series of ongoing international workshops focused on experimental, theoretical, and computational efforts in the challenging field of Warm Dense Matter (WDM). The workshop series started with an International Seminar on Warm Dense Matter in Vancouver, BC in 2000. Subsequent workshops were held in:
| Hamburg, Germany (2003) | Saint-Malo, France (2013) |
| Vancouver, BC (2005) | Kurashiki, Japan (2015) |
| Porquerolles, France (2007) | Vancouver, BC (2017) |
| Hakone, Japan (2009) | Travemunde, Germany (2019) |
| Pacific Grove, CA (2011) | Hyogo, Japan (2023) |
For 2025, the 12th International Workshop will return to the United States in picturesque and historic Santa Fe, NM, the oldest and highest elevation capital city in the US. The conference will begin on Tuesday, April 15, 2025 and will end on Friday, April 18, 2025.
This workshop aims to allow in-depth presentations and facilitate interactions between experimental, computational, and theoretical efforts in WDM research. The goals of this workshop include fostering increased communication and new collaborations between experimentalists, computationalists, and theorists working in WDM research; an assessment of the current state of the field in both theory and experiment; a deeper understanding of the formal theoretical and numerical issues concerning the modeling of warm dense matter; and attracting promising young researchers to this difficult and exciting field.
WDM occupies a loosely defined region of phase space intermediate between solid, liquid, gas, and plasma, and typically shares characteristics of two or more of these phases. WDM is generally associated with the combination of strongly coupled ions and moderately degenerate electrons, and careful attention to quantum physics and electronic structure is essential. The lack of a small perturbation parameter greatly limits approximate attempts at its accurate description.
Warm Dense Matter is ubiquitous in planetary science and astrophysics, particularly with respect to unresolved questions concerning the structure and age of the gas giants, the nature of exosolar planets, and the cosmochronology of white dwarf stars. Furthermore, since WDM resides at the intersection of solid state and high energy density physics (HEDP), many HEDP experiments pass through this difficult region of phase space. Thus, understanding and modeling WDM is key to the success of experiments on diverse HEDP facilities, including: high-energy laser facilities, such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and the OMEGA laser at the Laboratory for Laser Energetics; pulsed-power facilities, such as the Z machine at Sandia National Laboratories; ion-beam facilities, such as the NDCX-II at Lawrence Berkley National Laboratory; and X-ray Free Electron Laser (XFEL) facilities, such as the Linear Coherent Light Source (LCLS) at Stanford University and the European XFEL at Duetsches Elektronen-Synchrotron (DESY).
