Title: New Findings in Hydrogen in Extreme Environments

Abstract: Extreme pressures and temperatures produce profound effects on structure, bonding and electronic character of atoms and molecules, molding matter to make new materials. A growing number of novel materials and phenomena are being documented over the broad range of conditions using both static and dynamic multimegabar (e.g., >300 GPa) pressures that can now be generated in the laboratory. Because of its quantum character and putatively simple electronic properties, the behavior of hydrogen and hydrogen-rich systems in a variety of chemical environments at these pressures has been of particular interest. The results are leading to altogether new structures, electronic phenomena including high-temperature superconductivity, and potentially useful materials, with implications beyond condensed matter physics for planetary science, geoscience, and astrophysics.
