Realization of the Pascal based on Argon using a Fabry-Pérot refractometer
Isak Silander, Johan Zakrisson, Ove Axner +1
Based on a recent experimental determination of the static polarizability and a first-principles calculation of the frequency-dependent dipole polarizability of argon, this work pr…
STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
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…
Gas modulation refractometry (GAMOR) - On its ability to eliminate the influence of drifts
Ove Axner, Isak Silander, Clayton Forssén +2
Gas modulation refractometry (GAMOR) is a technique based on a dual-Fabry-Perot (FP) cavity (DFPC) for assessment of gas refractivity, density, and pressure that can alleviate sign…
Gas equilibration gas modulation refractometry (GEq-GAMOR) for assessment of pressure with sub-ppm precision
Isak Silander, Thomas Hausmaninger, Clayton Forssén +2
A novel realization of Gas Modulation Refractometry (GAMOR) that outperforms the original realization [Single Cavity Modulated GAMOR (SCM-GAMOR)], is presented. The reference measu…
Drift-Free Fabry-Perot-Cavity-based Optical Refractometry -- Accurate Expressions for Assessments of Gas Refractivity and Density
Ove Axner, Isak Silander, Thomas Hausmaninger +1
Recent advancements in the field of Fabry-Perot cavity based optical refractometry (OR), FPC-OR, comprising the use of proposed novel methodologies based on drift-free Dual FPC-OR…
Fast Switching Dual Fabry-Perot Cavity Optical Refractometry - Methodologies for Accurate Assessment of Gas Density
Isak Silander, Thomas Hausmaninger, Michael Bradley +2
Dual Fabry-Perot cavity based optical refractometry (DFPC-OR) has a high potential for assessments of gas density. However, drifts of the FP cavity often limit its performance. We…
Fast Switching Dual Fabry-Perot-Cavity-based Optical Refractometry for Assessment of Gas Refractivity and Density - Estimates of Its Precision, Accuracy, and Temperature Dependence
Martin Zelan, Isak Silander, Thomas Hausmaninger +1
Dual Fabry-Perot-Cavity-based Optical Refractometry (DFCB-OR) have been shown to have excellent potential for characterization of gases, in particular their refractivity and densit…
Superflow in a toroidal Bose-Einstein condensate: an atom circuit with a tunable weak link
A. Ramanathan, K. C. Wright, S. R. Muniz +6
We have created a long-lived (~ 40 s) persistent current in a toroidal Bose-Einstein condensate held in an all-optical trap. A repulsive optical barrier creates a tunable weak link…
