New class of laser beam doesn't follow normal laws of refraction
University of Central Florida researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels.

Since its discovery in 2014, phosphorene—a sheet of phosphorus atoms only a single atom thick—has intrigued scientists due to its unique optoelectronic anisotropy. In other words, electrons interact with light and move ...

If you heat a solid material enough, the thermal energy (latent heat) causes the material's molecules begin to break apart, forming a liquid. One of the most familiar examples of this phase transition from a well-ordered ...

University of Central Florida researchers have developed a way to control the speed of light. Not only can they speed up a pulse of light and slow it down, they can also make it travel backward.

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 ...

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 ...

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 ...
