Scientific Motivation
Quantum Molecular Dynamics (QMD) simulations [1,2,3]
in conjunction with the Kubo-Greenwood formulation have accurately reproduced
experimental results on electrical conductivity for a variety of species
in regimes where strong coupling and partial degeneracy effects become
important (Warm Dense Matter regime). This formulation has been extended
to the computation of optical properties such as reflectivities and absorption
coefficients [4]. That QMD approaches produce electrical and optical properties
consistent with the Equation of State (EOS) highlights a particularly attractive
advantage of these approaches for calibrating various modeling codes and
comparing with experiment over a wide range of conditions. More complex
problems, such as the dynamical and optical properties of mixtures, are
also particularly suited to this type of approach. While the QMD
methods have witnessed an intense period of development and implementation,
discovering the limits of their application remains an active and crucial
endeavor. The workshop aims at bringing together people involved
in the Quantum Molecular Dynamics simulation of the electrical and optical
of warm dense matter, experimentalists who provide the testbed for these
procedures as well as people invoved in the modeling of this state of matter.
