Proposal for matter-wave interferometry with a rare-earth-doped microparticle
Chris Overstreet
Matter-wave interferometers are sensitive probes of low energy physics and have been used for precise tests of gravity and quantum mechanics. These applications would benefit from…
Watt-class injection-locked diode laser system at 399 nm for atomic physics
Rose Ranson, Yifan Zhou, Michael Hesford +4
We demonstrate an injection-locked 399 nm laser system with up to 1 W output power and a locked power fraction of 0.57. The system consists of a high power, multimode diode laser t…
Magnetic recoil interferometer in a uniform gravitational field. Comment on Observation of the quantum equivalence principle for matter-waves
Peter Asenbaum, Chris Overstreet
The calculation of the phase shift of a matter-wave interferometer looks different for different coordinate choices or the addition of a uniform gravitational field, but the final…
Long-Baseline Atom Interferometry
Antun Balaz, Diego Blas, Oliver Buchmueller +50
Long-baseline atom interferometry is a promising technique for probing various aspects of fundamental physics, astrophysics and cosmology, including searches for ultralight dark ma…
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…
Search for monopole-dipole interactions with atom interferometry
Mahiro Abe, Jason M. Hogan, David E. Kaplan +2
Light, weakly coupled bosonic particles such as axions can mediate long range monopole-dipole interactions between matter and spins. We propose a new experimental method using atom…
Ytterbium atom interferometry for dark matter searches
Yifan Zhou, Rowan Ranson, Michalis Panagiotou +1
We analyze the projected sensitivity of a laboratory-scale ytterbium atom interferometer to scalar, vector, and axion dark matter signals. A frequency ratio measurement between two…
Matter waves and clocks do not observe uniform gravitational fields
Peter Asenbaum, Chris Overstreet, Mark A. Kasevich
In a uniform gravitational field, classical test objects fall universally. Any reference object or observer will fall in the same universal manner. Therefore, a uniform gravitation…
Inference of gravitational field superposition from quantum measurements
Chris Overstreet, Joseph Curti, Minjeong Kim +3
Experiments are beginning to probe the interaction of quantum particles with gravitational fields beyond the uniform-field regime. In non-relativistic quantum mechanics, the gravit…
A 40 W, 780 nm laser system with compensated dual beam splitters for atom interferometry
Minjeong Kim, Remy Notermans, Chris Overstreet +3
We demonstrate a narrow-linewidth 780 nm laser system with up to 40 W power and a frequency modulation bandwidth of 230 MHz. Efficient overlap on nonlinear optical elements combine…
Physically significant phase shifts in matter-wave interferometry
Chris Overstreet, Peter Asenbaum, Mark A. Kasevich
Many different formalisms exist for computing the phase of a matter-wave interferometer. However, it can be challenging to develop physical intuition about what a particular interf…
Atom-interferometric test of the equivalence principle at the level
Peter Asenbaum, Chris Overstreet, Minjeong Kim +2
Does gravity influence local measurements? We use a dual-species atom interferometer with of free-fall time to measure the relative acceleration between Rb and…
Effective inertial frame in an atom interferometric test of the equivalence principle
Chris Overstreet, Peter Asenbaum, Tim Kovachy +3
In an ideal test of the equivalence principle, the test masses fall in a common inertial frame. A real experiment is affected by gravity gradients, which introduce systematic error…
Phase shift in atom interferometry due to spacetime curvature
Peter Asenbaum, Chris Overstreet, Tim Kovachy +3
We present a single-source dual atom interferometer and utilize it as a gradiometer for precise gravitational measurements. The macroscopic separation between interfering atomic wa…
Response to "Verifying quantum superpositions at metre scales"
T. Kovachy, P. Asenbaum, C. Overstreet +5
The preceding BCA (Stamper-Kurn et. al., arXiv:1607.01454) asserts that our observation of interference contrast in a half-metre-scale atom interferometer (Kovachy et. al., Nature…
Matter wave lensing to picokelvin temperatures
Tim Kovachy, Jason M. Hogan, Alex Sugarbaker +4
Using a matter wave lens and a long time-of-flight, we cool an ensemble of Rb-87 atoms in two dimensions to an effective temperature of less than ~pK. A short pulse…
