Measurable signatures of quantum mechanics in a classical spacetime
Bassam Helou, Jun Luo, Hsien-Chi Yeh +4
We propose an optomechanics experiment that can search for signatures of a fundamentally classical theory of gravity and in particular of the many-body Schroedinger-Newton (SN) equ…
First Demonstration of Electrostatic Damping of Parametric Instability at Advanced LIGO
Carl Blair, Slawek Gras, Richard Abbott +16
Interferometric gravitational wave detectors operate with high optical power in their arms in order to achieve high shot-noise limited strain sensitivity. A significant limitation…
LISA pathfinder appreciably constrains collapse models
Bassam Helou, Bram Slagmolen, David E. McClelland +1
LISA Pathfinder's measurement of a relative acceleration noise between two free-falling test masses with a square root of the power spectral density of $5.2 \pm 0.1 \mbox{ fm s}^{-…
