Workshop: ELGAR, a future European Laboratory for Gravitation and Atom-interferometric Researchp

The ELGAR initiative supports the realization of a European underground infrastructure based on the latest progress in atomic physics, to study space-time and gravitation with the primary goal of detecting GWs in the infrasound band (0.1 Hz to 10 Hz). In view of organizing an answer to a forthcoming European research infrastructure call, the scope of the workshop will be to review the current developments related to the main technological bricks of the antenna.
