FFTArray: A Python Library for the Implementation of Discretized Multi-Dimensional Fourier Transforms
Stefan J. Seckmeyer, Christian Struckmann, Gabriel Müller +2
Partial differential equations describing the dynamics of physical systems rarely have closed-form solutions. Fourier spectral methods, which use Fast Fourier Transforms (FFTs) to…
Diffraction phase-free Bragg atom interferometry
Víctor J. Martínez-Lahuerta, Jan-Niclas Kirsten-Siemß, Klemens Hammerer +1
Bragg Diffraction of matter waves is an established technique used in the most accurate quantum sensors. It is also the method of choice to operate large-momentum-transfer, high-se…
Squeezing Enhancement in Lossy Multi-Path Atom Interferometers
Julian Günther, Jan-Niclas Kirsten-Siemß, Naceur Gaaloul +1
This paper explores the sensitivity gains afforded by spin-squeezed states in atom interferometry, in particular using Bragg diffraction. We introduce a generalised input-output fo…
Principal Component Analysis for Spatial Phase Reconstruction in Atom Interferometry
Stefan Seckmeyer, Holger Ahlers, Jan-Niclas Kirsten-Siemß +4
Atom interferometers are sensitive to a wide range of forces by encoding their signals in interference patterns of matter waves. To estimate the magnitude of these forces, the unde…
Atom interferometers in weakly curved spacetimes using Bragg diffraction and Bloch oscillations
Michael Werner, Philip K. Schwartz, Jan-Niclas Kirsten-Siemß +3
We present a systematic approach to determine all relativistic phases up to in light-pulse atom interferometers in weakly curved spacetime that are based on e…
Accurate and efficient Bloch-oscillation-enhanced atom interferometry
Florian Fitzek, Jan-Niclas Kirsten-Siemß, Ernst M. Rasel +2
Bloch oscillations of atoms in optical lattices are a powerful technique that can boost the sensitivity of atom interferometers to a wide range of signals by large momentum transfe…
