Physics 214 Lecture 11
... The electrons in a filled band cannot contribute to conduction, because with reasonable E fields they cannot be promoted to a higher kinetic energy. Therefore, at T = 0, Si is an insulator. At higher temperatures, however, electrons are thermally promoted into the conduction band: ...

... Still, Matt Leifer, a physicist at University College London who works on quantum information, says that the theorem tackles a big question in a simple and clean way. He also says that it could end up being as useful as Bell’s theorem, which turned out to have applications in quantum information the ...

One can easily understand this theorem: the homogeneous electric field does not accelerate the neutral atom. Therefore the field acting on the nucleus is equal to zero. The physical arguments as well as for ...
