Two-Photon Spectroscopy of Trapped Atomic Hydrogen

Two-photon spectroscopy of the 6S(1/2) ? 6D(5/2) transition of trapped atomic cesium.

Two-photon spectroscopy of atomic cesium confined and cooled in a magneto-optical trap is reported. The hyperfine structure of the 6D(5/2) state is determined with 1% accuracy. New capabilities for studying ac Stark shifts and kinetic transport for cold atoms are suggested.

Quantum interference of photon pairs from two remote trapped atomic ions

Trapped atomic ions are among the most attractive implementations of quantum bits for applications in quantuminformation processing, owing to their long trapping lifetimes and long coherence times. Although nearby trapped ions can be entangled through their Coulomb-coupled motion, it seems more natural to entangle remotely located ions through a coupling mediated by photons, eliminating the nee...

Two Photon Polarization Spectroscopy

2014 Dichroism and birefringence are studied for the case of a strong saturating laser and a linearly polarized weak probe laser interacting with a dilute gas. For linearly or circularly polarized saturating laser fields the optical analog of the Kerr or Faraday effect are obtained respectively. Two photon, Doppler-free polarization effects are studied for two and three level systems (J = 0 ~ J...

Photon Molecules in Atomic Gases Trapped Near Photonic Crystal Waveguides

Realizing systems that support robust, controlled interactions between individual photons is an exciting frontier of nonlinear optics. To this end, one approach that has emerged recently is to leverage atomic interactions to create strong and spatially nonlocal interactions between photons. In particular, effective photonic interactions have been successfully created via interactions between at...
