A High-Brightness Source of Narrowband, Identical
... We generated narrowband pairs of nearly identical photons at a rate of 5 104 pairs per second from a laser-cooled atomic ensemble inside an optical cavity. A two-photon interference experiment demonstrated that the photons could be made 90% indistinguishable, a key requirement for quantum informat ...

Steady-state quantum interference in resonance
... When a laser resonantly excites a many-level atomic system there are a number of quantum interference effects which can occur in the absorption and subsequent fluorescence. The possibility of transient quantum beats in the spontaneous emission following impulse excitation was first proposed by Breit ...

Electromagnetic ion-cyclotron instability in the presence of a parallel

The main advantages of this approach are to consider the energy transfer between wave and particles, along with the discussion of wave dispersion and th ...

Hagedorn: Molecular Propagation through Crossings and Avoided

This approximation fails if a wavepacket propagates through an electron energy level crossing or “avoided crossing.” We discuss the various types of crossings and avoided crossings and des ...
