Finite-Speed-of-Light Effects in Atom Interferometry: Diffraction Mechanisms and Resonance Conditions
Christian Niehof, Daniel Derr, Enno Giese
Light-pulse atom interferometers serve as tools for high-precision metrology and are targeting measurements of relativistic effects. This development is facilitated by extended int…
Balancing Quasi-Bragg Regime and Velocity Selectivity in Quantum-Enhanced Atom Interferometry
Christian Miguel Karres, Daniel Derr, Enno Giese
Spin squeezing in atomic ensembles enables atom interferometry with sensitivities below the shot-noise limit, but the associated entanglement is highly susceptible to loss, making…
Quantum Imaging Beyond the Standard-Quantum Limit and Phase Distillation
Simon Schaffrath, Daniel Derr, Markus Gräfe +1
Quantum sensing using non-linear interferometers offers the possibility of bicolour imaging, using light that never interacted with the object of interest, and provides a way to ac…

Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Generation of Josephson vortices in stacked toroidal Bose-Einstein condensates
Nataliia Bazhan, Anton Svetlichny, Dominik Pfeiffer +3
Coupled coaxially stacked toroidal condensates with persistent currents suggest an appealing physical platform for the investigation of various phenomena related to interacting sup…
Clock Transitions Versus Bragg Diffraction in Atom-interferometric Dark-matter Detection
Daniel Derr, Enno Giese
Atom interferometers with long baselines are envisioned to complement the ongoing search for dark matter. They rely on atomic manipulation based on internal (clock) transitions or…
Synthetic Quantum Holography with Undetected Light
Sebastian Töpfer, Sergio Tovar, Josué R. León Torres +4
Utilizing nonlinear interferometers for sensing with undetected light enables new sensing and imaging techniques in spectral ranges that are difficult to detect. To enhance this me…
Parameter Estimation from Amplitude Collapse in Correlated Matter-Wave Interference
Daniel Derr, Dominik Pfeiffer, Ludwig Lind +2
