Technical Proposal for the Atom Interferometer CERN Experiment (AICE) Facility
Gianluigi Arduini, Nadja Augst, Mark G. Bason +79
We present the technical proposal for the Atom Interferometer CERN Experiment (AICE), a m vertical atom interferometer to be installed against the wall of the PX…
Monolithic atom interferometry
Johannes Fiedler, Kim Lefmann, Wolf von Klitzing +1
Atom and, more recently, molecule interferometers are used in fundamental research and industrial applications. Most atom interferometers rely on gratings made from laser beams, wh…
Quantum Technologies in Space
Rainer Kaltenbaek, Antonio Acin, Laszlo Bacsardi +17
Recently, the European Commission supported by many European countries has announced large investments towards the commercialization of quantum technology (QT) to address and mitig…
Atomtronic circuits: from many-body physics to quantum technologies
Luigi Amico, Dana Anderson, Malcolm Boshier +4
Atomtronics is an emerging field that aims to manipulate ultracold atom moving in matter wave circuits for both fundamental studies in quantum science and technological application…
Decoherence-free radiofrequency dressed subspaces
G. A. Sinuco-Leon, H. Mas, S. Pandey +3
We study the spectral signatures and coherence properties of radiofrequency dressed hyperfine Zeeman sub-levels of 87Rb. Experimentally, we engineer combinations of static and RF m…
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 the Foundations of the Universe with Space Tests of the Equivalence Principle
Baptiste Battelier, Joël Bergé, Andrea Bertoldi +34
We present the scientific motivation for future space tests of the equivalence principle, and in particular the universality of free fall, at the level or better. Two po…
Matter-wave interferometers using TAAP rings
Patrick Navez, Saurabh Pandey, Hector Mas +3
We present two novel matter-wave Sagnac interferometers based on ring- shaped time-averaged adiabatic potentials (TAAP). For both the atoms are put into a superposition of two diff…
Design of a dual species atom interferometer for space
Thilo Schuldt, Christian Schubert, Markus Krutzik +54
Atom interferometers have a multitude of proposed applications in space including precise measurements of the Earth's gravitational field, in navigation & ranging, and in fundament…
STE-QUEST - Test of the Universality of Free Fall Using Cold Atom Interferometry
D. Aguilera, H. Ahlers, B. Battelier +63
The theory of general relativity describes macroscopic phenomena driven by the influence of gravity while quantum mechanics brilliantly accounts for microscopic effects. Despite th…
Fundamentals of Cavity-Enhanced Polarimetry for Parity-Nonconserving Optical Rotation Measurements: Application to Xe, Hg and I
L. Bougas, G. E. Katsoprinakis, W. von Klitzing +1
We present the theoretical basis of a cavity-enhanced polarimetric scheme for the measurement of parity-nonconserving (PNC) optical rotation. We discuss the possibility of detectin…
An ultra-bright atom laser
V. Bolpasi, N. K. Efremidis, M. J. Morrissey +4
We present a novel, ultra-bright atom-laser and ultra-cold thermal atom beam. Using rf-radiation we strongly couple the magnetic hyperfine levels of 87Rb atoms in a magnetically tr…
Time-Averaged Adiabatic Potentials: Versatile traps and waveguides for ultracold quantum gases

We demonstrate a novel class of trapping potentials, time-averaged adiabatic potentials (TAAP) which allows the generation of a large variety of traps and waveguides for ultracold…
Spontaneous emergence of angular momentum Josephson oscillations in coupled annular Bose-Einstein condensates
Igor Lesanovsky, Wolf von Klitzing
We investigate the nonlinear dynamics of two coupled annular Bose-Einstein condensates (BECs). For certain values of the coupling strength the nonrotating ground state is unstable…
