Abstract We propose in this White Paper a concept for space experiment using cold atoms to search ultra-light dark matter, and detect gravitational waves the frequency range between most sensitive ranges of LISA terrestrial LIGO/Virgo/KAGRA/INDIGO experiments. This interdisciplinary experiment, called Atomic Experiment Dark Matter Gravity Exploration (AEDGE), will also complement other planned searches exploit synergies with wave detectors. give examples extended sensitivity matter offered...
MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to explore fundamental physics with atom interferometry over 100-meter baseline. This novel detector will search for ultralight dark matter, test mechanics in new regimes, and serve as technology pathfinder future gravitational wave detectors previously unexplored frequency band. It combines techniques demonstrated state-of-the-art 10-meter-scale interferometers the latest technological advances of world's...
Single-photon atom gradiometry is a powerful experimental technique that can be employed to search for the oscillation of atomic transition energies induced by ultralight scalar dark matter (ULDM). In sub-Hz regime, background expected dominated gravity gradient noise (GGN), which arises as result mass fluctuations around experiment. this work, we model GGN surface Rayleigh waves, and construct likelihood-based analysis consistently folds into sensitivity estimates vertical gradiometers in...
In a previous paper from this laboratory it was suggested that when helium ions move under the influence of an electric field through gas, positive charge carried by ion does not remain long associated with single atom, but is repeatedly passed on to atom at collision process electron capture. This may be regarded as equivalent increase in target area presented atoms and must therefore lead reduction their mobility. When foreign given gas conditions resonance necessary for capture would...
Abstract We investigate and analyze site specific systematics for the MAGIS-100 atomic interferometry experiment at Fermi National Accelerator Laboratory. As atom interferometers move out of laboratory environment passive active mitigation noise sources must be implemented. To inform research development design, we measure ambient temperature, humidity, vibrations installation site. find that temperature fluctuations will necessitate enclosures critical subsystems a controlled laser room...
Atom interferometry is a quantum sensor technology that uses ultra-cold atoms placed in entangled states to detect minute changes local fields arising from gravitational waves and ultra-light dark matter. Their extreme sensitivity accelerations has been demonstrated for measurements of Newton's gravitation constant, tests the Equivalence Principle, measurement gravity gradients. The search matter requires interferometer baselines greater than approximately 100 m. In understanding fundamental...
Terrestrial long-baseline atom interferometer experiments are emerging as powerful tools for probing new fundamental physics, including searches dark matter and gravitational waves. In the frequency range relevant to these signals, gravity gradient noise (GGN) poses a significant challenge. While previous studies vertical instruments have focused on GGN induced by seismic waves, atmospheric fluctuations in pressure temperature also lead variations local gravity. this work, we advance...
Holographic interferometry using crystals of iron-doped lithium niobate is reported. The interferograms presented are produced via double-exposure Fourier transform holography in heavily doped without applied electric fields. Flow-field visualization used as an example application area.

Holograms that are highly resistant to optical erasure can be recorded in lithium niobate using thermal fixing or multiphoton techniques. In interferometry, such holograms have the potential of serving as permanent reference and thus reducing double-exposure interferometry single-exposure interferometry. We recently applied this technique thermally fixed iron-doped crystals niobate. First, scene is a Fourier transform hologram crystal. Then, same crystal volume, interest superimposed....
