Скачать или смотреть Dr. Arianna Gleason: New Lens on the Frontier of Matter in Extreme Conditions

As you move from the void of outer space through the atmosphere and into the interior of the earth, the pressure and energy density (energy per unit volume) inevitably increases. The pressure at the center of the earth is almost 4 million times that on the surface. At the center of the sun, the pressure is 200 billion times that on the surface of the earth. At these pressures and energy densities, most matter is in the form of a plasma. Matter at high energy density (HED) behaves in fascinatingly different ways than matter at ambient pressures. To say the least, these conditions are extreme. In this video, Dr. Arianna Gleason of the SLAC National Accelerator Laboratory and Stanford University describes methods to study and investigate how HED matter behaves and evolves over time. These conditions are probed with ultrashort lasers in order to freeze the motion of atoms and so better our understanding of HED matter.
