where [V.sup.[alpha].sub.j] is the transition matrix element between the virtual state j and a scattering state [alpha] and [E.sub.j] = [[epsilon].sub.j] + [[lambda].sub.j] is the zeroth-order approximation for the resonance energy, where [[epsilon].sub.j] and [[lambda].sub.j] are single particle QD levels for temporarily trapped carriers.
In this instance, if a photon of frequency v interacts with a molecule in the [S.sub.0], v = 0, state, the molecule goes to a virtual state, a nonexistent state represented by a dotted line (Figure 1(b)) and comes back very quickly (in a picosecond time scale) to the [S.sub.0], v = 0, state.
Their calculations, (http://scitation.aip.org/content/aip/journal/pop/23/9/10.1063/1.4962567) described in the latest issue of the journal Physics of Plasmas, are based on a concept called quantum electrodynamics (QED), which states that a strong electric field can convert matter-antimatter particles from a virtual state to a real one, where they are directly observable.
