Index of refraction engineering in five level DIGS atoms
Steven A. Sagona-Stophel, James Owen Weatherall, Christopher P. Search
We present a five level atomic system in which the index of refraction of a probe laser can be enhanced or reduced below unity with vanishing absorption in the region between pairs…
Lossless anomalous dispersion and an inversionless gain doublet via dressed interacting ground states (DIGS)
James Owen Weatherall, Christopher P. Search
Transparent media exhibiting anomalous dispersion have been of considerable interest since Wang, Kuzmich, and Dogariu [Nature {\bf 406}, 277 (2000)] first observed light propagate…
Quantum control of dispersion in electromagnetically induced transparency via interacting dressed ground states
James Owen Weatherall, Christopher P. Search
We offer a general treatment of electromagnetically induced transparency (EIT) in a five level system consisting of four metastable ground states. Two additional RF/microwave field…
Quantum control of EIT dispersion via atomic tunneling in a double-well Bose-Einstein condensate
James Owen Weatherall, Christopher P. Search, Markku Jaaskelainen
Electromagnetically induced transparency (EIT) is an important tool for controlling light propagation and nonlinear wave mixing in atomic gases with potential applications ranging…
Diffraction of ultra-cold fermions by quantized light fields: Standing versus traveling waves
D. Meiser, C. P. Search, P. Meystre
We study the diffraction of quantum degenerate fermionic atoms off of quantized light fields in an optical cavity. We compare the case of a linear cavity with standing wave modes t…
