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...
We report the first realization of large momentum transfer (LMT) clock atom interferometry. Using single-photon interactions on strontium ^{1}S_{0}-^{3}P_{1} transition, we demonstrate Mach-Zehnder interferometers with state-of-the-art separation up to 141 ℏk and gradiometers 81 ℏk. Moreover, circumvent excited state decay limitations extend gradiometer duration 50 times lifetime. Because broad velocity acceptance interferometry pulses, all experiments are performed laser-cooled atoms at a...
Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement periodic atom-light coupling to realize atom optics on strontium ^{1}S_{0}-^{3}P_{1} transition. These reach pulse efficiencies above 99.4% over wide range frequency offsets between light and atomic resonance, even under strong driving where this detuning is order Rabi frequency. Moreover, we use compensate differential Doppler shifts in large momentum transfer...
A phase-only spatial light modulator (SLM) provides a powerful way to shape laser beams into arbitrary intensity patterns but at the cost of hard computational problem determining an appropriate SLM phase. Here, we show that optimal transport methods can generate approximate solutions this serve as excellent initializations for iterative phase retrieval algorithms, yielding vortex-free with superior accuracy and efficiency. Additionally, analogous algorithms be used measure input beam...
The ${{^1\mathrm{S}_0}\!-\!{^3\mathrm{P}_0}}$ clock transition in strontium serves as the foundation for world's best atomic clocks and gravitational wave detector concepts atom interferometry. This is weakly allowed fermionic isotope $^{87}$Sr but strongly forbidden bosonic isotopes. Here we demonstrate coherent excitation of ${}^{88}$Sr using a novel collinear three-photon process weak magnetic field. We observe Rabi oscillations with frequencies up to $50~\text{kHz}$...

Given a random k-dimensional cross-section of hypercube, what is its expected number vertices? We show that, for suitable distribution slices, the answer $2^k$, independent dimension hypercube.
We explore new ways of regulating defect behavior in systems conservation laws. Contrary to usual regularization schemes (such as a vanishing viscosity limit), which attempt control defects by making them smoother, our result are \textit{more singular}, and we thus refer such "irregularizations". In particular, seek produce \textit{delta shock} satisfy condition \textit{stationarity}. motivated pursue exotic physical example arising from dislocation dynamics materials physics, describe.

For matrices with all nonnegative entries, the Perron-Frobenius theorem guarantees existence of an eigenvector components. We show that such is also guaranteed for a very different class matrices, namely real symmetric exactly two eigenvalues. prove partial converse, among any more than eigenvalues there exist some having no eigenvector.
