Very-High-Frequency Gravitational Waves from Multi-Monodromy Inflation
Guido D'Amico, Andrew A. Geraci, Nemanja Kaloper +1
We show that in multi-stage axion monodromy inflation an interruption near the end of the penultimate stage can lead to a spike in the gravitational wave background. These gravitat…
Searching for Ultralight Dark Matter with MOLeQuTE: a Massive Optically Levitated Quantum Tabletop Experiment
Louis Hamaide, Hannah Banks, Peter Barker +1
Many well theoretically motivated models of ultralight dark matter are expected to give rise to feeble oscillatory forces on macroscopic objects. Optically trapped sensors have hig…
US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Resonant detection of axion mediated forces with Nuclear Magnetic Resonance
Asimina Arvanitaki, Andrew A. Geraci
We describe a method based on precision magnetometry that can extend the search for axion-mediated spin-dependent forces by several orders of magnitude. By combining techniques use…
Short-range force detection using optically-cooled levitated microspheres
Andrew A. Geraci, Scott B. Papp, John Kitching
We propose an experiment using optically trapped and cooled dielectric microspheres for the detection of short-range forces. The center-of-mass motion of a microsphere trapped in v…
Testing Atom and Neutron Neutrality with Atom Interferometry
Asimina Arvanitaki, Savas Dimopoulos, Andrew A. Geraci +2
We propose an atom-interferometry experiment based on the scalar Aharonov-Bohm effect which detects an atom charge at the 10^{-28}e level, and improves the current laboratory limit…
