In a previous article, we have reported on the first subpicometer interferometer flown in
space as part of ESA's LISA Pathfinder mission, and have shown the residual sensor noise …

In the months since the publication of the first results, the noise performance of LISA
Pathfinder has improved because of reduced Brownian noise due to the continued decrease …

We report the first results of the LISA Pathfinder in-flight experiment. The results demonstrate
that two free-falling reference test masses, such as those needed for a space-based …

High-precision electrostatic accelerometers have achieved remarkable success in satellite
Earth gravity field recovery missions. Ultralow-noise inertial sensors play important roles in …

We present an in-depth analysis of the LISA Pathfinder differential acceleration performance
over the entire course of its science operations, spanning approximately 500 days. We …

Matter-wave interferometers with large momentum transfers, irrespective of specific
implementations, will face a universal dephasing due to relative accelerations between the …

This paper addresses a simple question: how small can one make a gravitational source
mass and still detect its gravitational coupling to a nearby test mass? We describe an …

The continuous spontaneous localization (CSL) model is the best known and studied among
collapse models, which modify quantum mechanics and identify the fundamental reasons …

This paper presents a quantitative assessment of the performance of the upcoming LISA
Pathfinder geodesic explorer mission. The findings are based on the results of extensive …

We report on the performance of the capacitive gap-sensing system of the Gravitational
Reference Sensor on board the LISA Pathfinder spacecraft. From in-flight measurements …
