Recent cosmic microwave background data favours a blueshifted primeval perturbation spectrum with an indexn>1, which implies that the equation of state of domina
The effects of the electromagnetically induced transparency and dispersion of a A-type three-level atomic system are experimentally measured with a vapour cell
We propose a new formula to describe the dynamics of holographic grating formation under low intensity pulse exposures in cationic photopolymers, in which the d
