Searching for screened scalar forces with long-baseline atom interferometers
Hannah Banks, John Carlton, Benjamin Elder +2
Screened scalars are ubiquitous in many dark-sector models. They give rise to non-trivial fifth forces whilst evading experimental constraints through density-dependent screening m…
Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Massive graviton dark matter searches with long-baseline atom interferometers
Diego Blas, John Carlton, Christopher McCabe
Atom interferometers offer exceptional sensitivity to ultra-light dark matter (ULDM) by precisely measuring effects on atomic systems. Previous studies have demonstrated their capa…
Clear skies ahead: characterizing atmospheric gravity gradient noise for vertical atom interferometers
John Carlton, Valerie Gibson, Tim Kovachy +2
Terrestrial long-baseline atom interferometer experiments are emerging as powerful tools for probing new fundamental physics, including searches for dark matter and gravitational w…
