Peering into plasma mirrors

When light interacts with a mirror which is moving towards it at a speed close to the speed of light, its wavelength is shifted into the extreme ultraviolet region of the spectrum. This effect was first predicted by Albert ...

Light pulses provide a new route to enhance superconductivity

Under normal electron band theory, Mott insulators ought to conduct electricity, but they do not due to interactions among their electrons. But now, scientists from the RIKEN Cluster for Pioneering Research have shown that ...

One of the world's fastest cameras captures motion of electrons

During the conversion of light into electricity, such as in solar cells, a large part of the input light energy is lost. This is due to the behaviour of electrons inside of materials. If light hits a material, it stimulates ...

Brief reflections from a plasma mirror

When a dense sheet of electrons is accelerated to almost the speed of light, it acts as a reflective surface. Such a 'plasma mirror' can be used to manipulate light. Now an international team of physicists from the Max Planck ...
