Abstract :
We demonstrate electromagnetically-induced anomalous quantum dynamics of an exciton in a photonic band gap quantum well heterostructure. The exciton can be captured in k¿ -space by emission and re-absorption of virtual photons near a photonic band edge, lowering its energy by 1¿10meV and its effective mass by 4¿5 orders of magnitude.
