Atom interferometry tests of local Lorentz invariance in gravity and electrodynamics
Keng-Yeow Chung, Sheng-wey Chiow, Sven Herrmann +2
We present atom-interferometer tests of the local Lorentz invariance of post-Newtonian gravity. An experiment probing for anomalous vertical gravity on Earth, which has already bee…
Atom interferometers with scalable enclosed area
Holger Mueller, Sheng-wey Chiow, Sven Herrmann +1
Bloch oscillations (i.e., coherent acceleration of matter waves by an optical lattice) and Bragg diffraction are integrated into light-pulse atom interferometers with large momentu…
Noise-Immune Conjugate Large-Area Atom Interferometers
Sven Herrmann, Sheng-wey Chiow, Steven Chu +1
We present a pair of simultaneous conjugate Ramsey-Borde atom interferometers (SCI) using large (20\hbar k)-momentum transfer (LMT) beam splitters, where \hbar k is the photon mome…
6 W, 1 kHz linewidth, tunable continuous-wave near-infrared laser
Sheng-wey Chiow, Sven Herrmann, Holger Mueller +1
A modified Coherent 899-21 titanium sapphire laser is injection locked to produce 6-6.5 W of single-frequency light at 852 nm. After closed-loop amplitude control and frequency sta…
