Can we model a metal by a black-body at thermal Fermi temperature?

A black-body absorbs and re-emit radiations at all wavelengths. The intensity due to a black-body is due to Boltzmann-Stefan law. Metals are modeled by a system of free electrons. The uppermost...

Does light have mass inside a stationary and accelerating conductor?

Light is known to be massless in vacuum. However, when it enters a conductor, does it still have zero mass? In a transparent medium, the speed of light is less that c, which would imply that light...
