When you make conducting wires thinner, their electrical resistance goes up. This is Ohm's law, and it is generally right. An important exception is at very low temperatures, where the mobility of electrons increases when ...

If topological insulators are doped with impurities that possess magnetic properties, they lose their conductivity. Yet contrary to what has been assumed thus far, it is not the magnetism that leads to this. This has been ...
