We outline the experimental concept and key scientific capabilities of AION (Atom Interferometer Observatory Network), a proposed programme using cold strontium atoms to search for ultra-light dark matter, explore gravitational waves in mid-frequency range between peak sensitivities LISA LIGO/Virgo/ KAGRA/INDIGO/Einstein Telescope/Cosmic Explorer experiments, probe other frontiers fundamental physics. would complement planned searches as well mergers involving intermediate-mass black holes...
Abstract We propose in this White Paper a concept for space experiment using cold atoms to search ultra-light dark matter, and detect gravitational waves the frequency range between most sensitive ranges of LISA terrestrial LIGO/Virgo/KAGRA/INDIGO experiments. This interdisciplinary experiment, called Atomic Experiment Dark Matter Gravity Exploration (AEDGE), will also complement other planned searches exploit synergies with wave detectors. give examples extended sensitivity matter offered...
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around world to discuss exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter gravitational waves. primary objective was lay groundwork an international TVLBAI proto-collaboration. collaboration aims unite researchers different institutions strategize...
Abstract We summarise the discussions at a virtual Community Workshop on Cold Atoms in Space concerning status of cold atom technologies, prospective scientific and societal opportunities offered by their deployment space, developments needed before atoms could be operated space. The technologies discussed include atomic clocks, quantum gravimeters accelerometers, interferometers. Prospective applications metrology, geodesy measurement terrestrial mass change due to, e.g., climate change,...
This paper outlines the centralized design and production of ultra-high-vacuum sidearm laser-stabilization systems for AION Ultra-Cold Strontium Laboratories. Commissioning data on residual gas steady-state pressures in chambers, magnetic field quality, laser stabilization, loading rate 3D magneto-optical trap are presented. Streamlining stabilization enabled Collaboration to build equip parallel five state-of-the-art Laboratories within 24 months by leveraging key expertise collaboration....
