Atom-wave diffraction between the Raman-Nath and the Bragg regime: Effective Rabi frequency, losses, and phase shifts
We present an analytic theory of the diffraction of (matter) waves by a lattice in the ``quasi-Bragg" regime, by which we mean the transition region between the long-interaction Bragg andExpand

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.
Lorentz invariance violation and charge (non)conservation: A general theoretical frame for extensions of the Maxwell equations
All quantum gravity approaches lead to small modifications in the standard laws of physics which in most cases lead to violations of Lorentz invariance. One particular example is the extendedExpand
Atom interferometry tests of local Lorentz invariance in gravity and electrodynamics
We present atom-interferometer tests of the local Lorentz invariance of post-Newtonian gravity. An experiment probing for anomalous vertical gravity on Earth, which has already been performed, usesExpand
Quantum test of the equivalence principle and space-time aboard the International Space Station
We describe the Quantum Test of the Equivalence principle and Space Time (QTEST), a concept for an atom interferometry mission on the International Space Station (ISS). The primary science objectiveExpand
Optical cavity tests of Lorentz invariance for the electron
A hypothetical violation of Lorentz invariance in the electrons' equation of motion (expressed within the Lorentz-violating extension of the standard model) leads to a change of the geometry ofExpand
Bloch beamsplitters and dual-lattice methods for atom interferometry
Using two independently accelerated optical lattices, we produce a coherent beamsplitter for atom interferometry, as well as coherent reflection and recombination of matter waves when the latticesExpand
Fast high-voltage amplifiers for driving electro-optic modulators
We describe five high-voltage (60 to 550 V peak to peak), high-speed (1–300 ns risetime; 1.3–300 MHz bandwidth) linear amplifiers for driving capacitive or resistive loads such as electro-opticExpand
A new photon recoil experiment: towards a determination of the fine structure constant
We report on progress towards a measurement of the fine structure constant α to an accuracy of 5×10-10 or better by measuring the ratio h/mCs of the Planck constant h to the mass of the cesium atomExpand
Testing Lorentz invariance by the use of vacuum and matter filled cavity resonators
We consider tests of Lorentz invariance for the photon and fermion sector that use vacuum and matter-filled cavities. Assumptions on the wave function of the electrons in crystals are eliminated fromExpand
