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…
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…
Silicon microcavity arrays with open access and a finesse of half a million
G. Wachter, S. Kuhn, S. Minniberger +10
Optical resonators are increasingly important tools in science and technology. Their applications range from laser physics, atomic clocks, molecular spectroscopy, and single-photon…
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…
Cavity-assisted manipulation of freely rotating silicon nanorods in high vacuum
Stefan Kuhn, Peter Asenbaum, Alon Kosloff +7
Optical control of nanoscale objects has recently developed into a thriving field of research with far-reaching promises for precision measurements, fundamental quantum physics and…
Real-time single-molecule imaging of quantum interference
Thomas Juffmann, Adriana Milic, Michael Müllneritsch +6
The observation of interference patterns in double-slit experiments with massive particles is generally regarded as the ultimate demonstration of the quantum nature of these object…
Cavity cooling of free silicon nanoparticles in high-vacuum
Peter Asenbaum, Stefan Kuhn, Stefan Nimmrichter +2
Laser cooling has given a boost to atomic physics throughout the last thirty years since it allows one to prepare atoms in motional states which can only be described by quantum me…
Master Equation for the Motion of a Polarizable Particle in a Multimode Cavity
Stefan Nimmrichter, Klemens Hammerer, Peter Asenbaum +2
We derive a master equation for the motion of a polarizable particle weakly interacting with one or several strongly pumped cavity modes. We focus here on massive particles with co…
