Description:
Explore advanced dynamic compression studies conducted using the Sandia Z Machine in this comprehensive lecture. Delve into the coupling of pulsed power experiments with condensed matter theory to investigate extreme states of matter. Learn about high-precision Hugoniot experiments on deuterium, the evaluation of exchange-correlation functionals at the molecular-to-atomic transition, and the direct observation of a liquid-liquid insulator-to-metal transition in dense liquid deuterium. Examine multiple-shock electrical conductivity measurements probing intermediate temperature and density regimes. Gain insights into experimental configurations, data analysis techniques, and the integration of theory, computation, and experiment in shock physics research.
