Gravitational wave detectors are already operating at interesting sensitivity levels, and they
have an upgrade path that should result in secure detections by 2014. We review the …

Gravitational wave science should transform in this decade from a study of what has not
been seen to a full-fledged field of astronomy in which detected signals reveal the nature of …

Gravitational waves (GW) were predicted by Einstein [1] as a consequence of the theory of
General Relativity; its geometrical interpretation states that gravitation is the result of the …

We show that gravitational wave detectors based on a type of atom interferometry are
sensitive to ultralight scalar dark matter. Such dark matter can cause temporal oscillations in …

Wave function collapse models postulate a fundamental breakdown of the quantum
superposition principle at the macroscale. Therefore, experimental tests of collapse models …

The fine-structure constant and the electron mass in string theory are determined by the
values of scalar fields called moduli. If the dark matter takes on the form of such a light …

We discuss the use of optical cavities as tools to search for dark matter (DM) composed of
virialized ultralight fields (VULFs). Such fields could lead to oscillating fundamental …

This work describes the operation of a high frequency gravitational wave detector based on
a cryogenic bulk acoustic wave cavity and reports observation of rare events during 153 …

Different approaches to quantum gravity, such as string theory, and loop quantum gravity, as
well as doubly special relativity and gedanken experiments in black-hole physics,,, all …

A search for a new scalar field, called moduli, has been performed using the cryogenic
resonant-mass AURIGA detector. Predicted by string theory, moduli may provide a …
