Extreme States of Matter on Earth and in Space Abgesagt

Reihe: Global Solutions
Referent/in: Vladimir E. Fortov (Russian Federation)
Inhalt:

Plasma at extremely high pressures and temperatures plays an important role for understanding the structure and evolution of astrophysical objects: neutron and quark “strange” stars, black halls, pulsars, supernovas, magnetars, giant-planets, exoplanets, and many technologies. Pulsed methods for generation of extremely high pressures in the dense nonideal plasma based on the compression and heating of matter in intense shock waves and waves of adiabatic expansion, are discussed. To generate shock impulses in the megabar pressure range the cylindrical and spherical condensed high explosive charges, laser and corpuscular beams, high velocity impacts, and soft X-rays are broadly   used. The experimental data obtained by the shock wave techniques and the physical models of strongly coupled plasma physical properties at high pressures, temperatures and energy densities are discussed: the metallization and dielectrization of strongly compressed plasma, high temperature thermodynamics and phase transitions, deformation of energy spectrum of compressed ions and atoms. We present the plasma physical properties and phase transformation in a broad range of pressure up to 1030 bar – few microseconds after Big-Bang. The analysis of plasma properties in the astrophysical objects and their transformation are presented. The properties of quark-gluon plasma which is generated as a result of relativistic ion collisions are analyzed. Based on the experimental data the wide-range semi-empirical equations of state and the states and models of plasma transport properties are constructed. These semi-empirical models were used for multidimensional numerical simulation of pulsed high-energy processes.

Vladimir E. Fortov

Vladimir E. Fortov is a well-known scientist in the field of plasma and space physics, extremely high pressures and temperatures, physics and chemistry of strong shock and detonation waves, pulsed energetics.

He was Head of the Division of Energetics, Machinery, Mechanics and Control Systems of Russian Academy of Sciences and Director of the Joint Institute for High Temperature of RAS. Vladimir Fortov and his Institute participated in the international Russian, French, German, Hungarian Space project VEGA - investigation of Halley comet.

He was awarded many prizes, including the L.P. Karpinsky International Prize in Physics and Chemistry; International P. Bridgeman Prize for Achievements in High Pressure Physics and Technology; International Max Planck Award for Physics. He is also a member of the European Academy of Sciences, Arts and Letters and of the Max Planck Society. He was the Minister of Science and Technology and Deputy Prime Minister of Russia from 1996 to 1998.
