Virtual photon contribution to frictional drag in double-layer devices / A.Donarini, R.Ferrari, A.P.Jauho, L.G.Molinari. - In: PHYSICS LETTERS A. - ISSN 0375-9601. - 312:1-2(2003), pp. 123-129.
Abstract:
Frictional drag between coupled two-dimensional charge systems is commonly viewed as a second order effect arising either from screened Coulomb interaction, or phonon exchange. We point out that for single-photon exchange the first order contribution does not have to vanish even at T = 0, and evaluate this contribution for simple models.
