Some quantum mechanical aspects of frictional force between parallel metallic slabs

We present a new derivation of the friction force between two metallic slabs moving with constant relative parallel velocity, based on T=0 quantum field theory formalism. By including fully nonlocal description of dynamically screened electron fluctuations in the slab, and avoiding the usual matching condition procedure, we generalise previous expressions for the friction force, to which our results reduce in the local limit.
