Engineers at Caltech have shown that atoms in optical cavities -- tiny boxes for light -- could lead to the creation of a quantum internet. Their National Science Foundation-funded work...
Long range transport of ultra cold atoms in a far-detuned 1D optical lattice
Long range transport ultra cold atoms far-detuned 1D optical lattice Atomic Physics
2012/4/27
We present a novel method to transport ultra cold atoms in a focused optical lattice over macroscopic distances of many Rayleigh ranges. With this method ultra cold atoms were transported over 5 cm in...
Optical transitions in highly-charged californium ions with high sensitivity to variation of the fine-structure constant
Optical transitions highly-charged californium ions variation of the fine-structure constant Atomic Physics
2012/4/19
We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...

Optical Magnetometer Array Fetal Magnetocardiography
2012/2/28
We describe an array of spin-exchange relaxation free optical magnetometers designed for detection of fetal magnetocardiography (fMCG) signals. The individual magnetometers are configured with a small...
We propose blue-detuned optical traps that are suitable for trapping of both ground state and Rydberg excited atoms. Addition of a background compensation field or suitable choice of the trap geometry...
Spectrally narrow, long-term stable optical frequency reference based on a Eu$^{3+}$:Y$_{2}$SiO$_{5}$ crystal at cryogenic temperature
Spectrally narrow long-term stable optical frequency reference cryogenic temperature

Abstract: Using an ultrastable continuous-wave laser at 580 nm we performed spectral hole burning of Eu$^{3+}$:Y$_{2}$SiO$_{5}$ at very high spectral resolution. Essential parameters determining the u...
Rydberg Spectroscopy in an Optical Lattice: Blackbody Thermometry for Atomic Clocks
Rydberg Spectroscopy Optical Lattice Blackbody Thermometry Atomic Clocks
2011/8/17
Abstract: We show that optical spectroscopy of Rydberg states can provide accurate {\em in situ} thermometry at room-temperature. Transitions from a metastable state to Rydberg states with principal q...
Theoretical description of two ultracold atoms in finite 3D optical lattices using realistic interatomic interaction potentials

2011/8/4
Abstract: A theoretical approach is described for an exact numerical treatment of a pair of ultracold atoms interacting via a central potential that are trapped in a finite three-dimensional optical l...
Characterization of excited states of ultracold atoms in optical lattices
Characterization of excited states ultracold atoms optical lattices
2011/9/15
Loading ultracold atoms in an optical lattice from a Bose-Einstein condensate is generally a nonadiabatic process resulting in the dynamical excitation of a wavepacket, a combination of several eigens...
Optical Excitation and Decay Dynamics of Ytterbium Atoms Embedded in a Solid Neon Matrix
Ytterbium Atoms Embedded Optical Excitation and Decay Dynamics
2011/9/2
Neutral ytterbium atoms embedded in solid neon qualitatively retain the structure of free atoms. Despite the atom-solid interaction, the 6s6p 3P0 level is found to remain metastable with its lifetimes...
We have investigated the all-optical generation of ions by photo-ionisation of atoms generated by pulsed laser ablation. A direct comparison between a re-
sistively heated oven source and pulsed lase...

Optical Forc Two-level Atoms Few-cycle Pulsed Gaussian Laser field
2011/9/1
We report a study on light force on a beam of neutral two-level atoms superimposed upon a few-cycle pulsed Gaussian laser field under both resonant and off-resonant condition. The phenomena of focusin...
Probing degenerate two-level atomic media by coherent optical heterodyning

2011/8/29
We analyze how light-induced coherent population oscillations and ground-state Zeeman coherence in an atomic medium with degenerate two-level transitions can modify spectra of applied cw resonant radi...

The dressed atom binary phase modulator
2010/11/16
Nanophotonic technologies offer great promise for ultra-low power optical signal processing, but relatively few nonlinear-optical phenomena have yet been explored as bases for robust digital modulati...
