Exploration of Ultra-High Pressure Condensed Matter Research with High-Power Laser

Abstract

Laser-driven dynamic compression has been used to study extreme conditions of various materials. Very high pressures and temperatures can be generated up to more than 10³ GPa and 10⁵ K, respectively. This approach, which has been developed as a strong driving force in the inertial confinement fusion research, now provides a very wide range of pressures, densities and even low temperatures. This review presents a part of the past 10-year works on Hugoniot based equation-of-state (EOS), current trends of the off-Hugoniot generation and measurements, and a future perspective of high-pressure condensed matter research toward undiscovered metallic materials in the Osaka University.
