International audienceAbstract Quantum fluctuations of the electromagnetic field are known to produce the atomic Lamb shift. We here reveal their iconic signature in semiconductor physics, through the blue-shift they produce to optically bright excitons, thus lifting the energy of these excitons above their dark counterparts. The electromagnetic field here acts in its full complexity: in addition to its longitudinal part via inter band virtual Coulomb processes, the transverse part —which has been missed up to now— also acts via resonant and nonresonant virtual photons . These two parts beautifully combine to produce a bright exciton blue-shift independent of the exciton wave vector direction. Our work readily leads to a striking prediction...
