Workshop on

Understanding Condensed Matter Dynamics at the Microscopic Level

June 23-24, 2008
Room A1100, Building 401
Advanced Photon Source, Argonne National Laboratory

Yogi Gupta (WSU), Christian Mailhiot (DOE-NNSA), Dennis Mills (APS)

Background and Purpose:
Understanding material behavior under extreme conditions is central to modern materials research, as highlighted in a recent DOE workshop on "Basic Research Needs for Materials under Extreme Environments" (June, 2007, Washington D.C., Over the past decade or two, a large number of new materials and novel phenomena have been discovered and predicted at extreme conditions, paralleling advancements in high-pressure technologies, the nation's large-scale experimental user facilities, condensed matter theories, and high-performance computers. Yet, because of the single event and destructive nature of the experiments, gaining microscopic insights into dynamic materials response has been a significant scientific challenge, despite unprecedented scientific opportunities for mechanistic understanding of material phenomena in short time and length scales.

The goal of the Workshop is, therefore, to see how national facilities like the APS can be utilized to examine and understand the real time response of dynamically compressed materials at the microscopic level. Presentations will focus on scientific challenges and opportunities in understanding the dynamic response of materials subjected to large compressions, high temperatures, and large deformations on short time scales (ps to µs). The extreme conditions encountered under dynamic compressions reveal the delicate balance between mechanical and thermal energies leading to novel states of matter; yet, the short time scales inherent in rapid dynamic loading exploit the mechanistic insights into the material's transformation.

To be discussed in this workshop are fundamental scientific challenges and technology needs to study condensed matter under dynamic compression, including:

  • EOS, melting, and other phase transitions
  • Deformation, fracture, and microstructures
  • Electronic structures, chemical bondings, and reactions
  • Kinetics, metastabilities, and supercooled/heated solids far from equilibrium
  • New technology developments for shock and shockless compression
  • Enabling national facilities for real-time structural studies

Technical Program:
It is a one and a half day workshop, consisting of invited talks and posters. Participants are from universities, national laboratories, and research institutes in the U.S. and abroad.

As of June 2, invited speakers and poster presenters include:
