A trapped atom interferometer with ultracold Sr atoms
Xian Zhang, Ruben Pablo del Aguila, Tommaso Mazzoni +2
We report on a trapped atom interferometer based on Bragg diffraction and Bloch oscillations with alkaline-earth-metal atoms. We use a Ramsey-Bordé Bragg interferometer with $^{88}…
Measurement of the Gravity-Field Curvature by Atom Interferometry
G. Rosi, L. Cacciapuoti, F. Sorrentino +3
We present the first direct measurement of the gravity-field curvature based on three conjugated atom interferometers. Three atomic clouds launched in the vertical direction are si…
Precision Measurement of the Newtonian Gravitational Constant Using Cold Atoms
G. Rosi, F. Sorrentino, L. Cacciapuoti +2
About 300 experiments have tried to determine the value of the Newtonian gravitational constant, G, so far, but large discrepancies in the results have made it impossible to know i…
A high stability semiconductor laser system for a Sr-based optical lattice clock
Marco. G. Tarallo, Nicola Poli, Marco Schioppo +1
We describe a frequency stabilized diode laser at 698 nm used for high resolution spectroscopy of the 1S0-3P0 strontium clock transition. For the laser stabilization we use state-o…
