Ohm’s law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the ...

Scientists at Tokyo Tech experimentally verify the existence of exotic surface conduction states in topological semimetals (TSMs), materials that lie at the boundary between conductors and ...

For example, in so-called Mott insulators, ... it takes only a single oscillation of light to disrupt the electronic order of a material and turn an insulator into a metal-like conductor.

Even in the lab, topological insulators require less exotic conditions than had been thought. Jeroen van den Brink, a physicist at the Leibniz Institute for Solid State and Materials Research in ...
