Technologies for the ELGAR large scale atom interferometer array
B. Canuel, S. Abend, P. Amaro-Seoane +56
We proposed the European Laboratory for Gravitation and Atom-interferometric Research (ELGAR), an array of atom gradiometers aimed at studying space-time and gravitation with the p…
ELGAR -- a European Laboratory for Gravitation and Atom-interferometric Research
B. Canuel, S. Abend, P. Amaro-Seoane +55
Gravitational Waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection band…
Exploring gravity with the MIGA large scale atom interferometer
B. Canuel, A. Bertoldi, L. Amand +22
We present an underground long baseline atom interferometer to study gravity at large scale. The hybrid atom-laser antenna will use several atom interferometers simultaneously inte…
Low Frequency Gravitational Wave Detection With Ground Based Atom Interferometer Arrays
W. Chaibi, R. Geiger, B. Canuel +3
We propose a new detection strategy for gravitational waves (GWs) below few Hertz based on a correlated array of atom interferometers (AIs). Our proposal allows to reduce the Newto…
Matter-wave laser Interferometric Gravitation Antenna (MIGA): New perspectives for fundamental physics and geosciences
R. Geiger, L. Amand, A. Bertoldi +13
The MIGA project aims at demonstrating precision measurements of gravity with cold atom sensors in a large scale instrument and at studying the associated applications in geoscienc…
Low noise amplication of an optically carried microwave signal: application to atom interferometry
Thomas Lévèque, Alexandre Gauguet, Walid Chaibi +1
In this paper, we report a new scheme to amplify a microwave signal carried on a laser light at =852nm. The amplification is done via a semiconductor tapered amplifier and this…
