Fermion quantum field theory on curved and non-inertial backgrounds in standard-Minkowski form
Fabio Di Pumpo, Tobias Asano, Alexander Friedrich +2
Quantum field theory on curved and non-inertial backgrounds contains background- and foliation-dependent quantities in the canonical Lagrangian, the hypersurface inner product and…
Decoupling of External and Internal Dynamics in Driven Two-level Systems
Samuel Böhringer, Alexander Friedrich
We show how a laser driven two-level system including quantized external degrees of freedom for each state can be decoupled into a set of oscillator equations acting only on the ex…
Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary
Sven Abend, Baptiste Allard, Iván Alonso +250
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world…
Optimal baseline exploitation in vertical dark-matter detectors based on atom interferometry
Fabio Di Pumpo, Alexander Friedrich, Enno Giese
Several terrestrial detectors for gravitational waves and dark matter based on long-baseline atom interferometry are currently in the final planning stages or already under constru…
The Wave Functional of the Vacuum in a Resonator
Alexander Friedrich, Daniela Moll, Matthias Freyberger +2
We show that despite the fundamentally different situations, the wave functional of the vacuum in a resonator is identical to that of free space. The infinite product of Gaussian g…
Tunneling Gravimetry
Patrik Schach, Alexander Friedrich, Jason R. Williams +2
We examine the prospects of utilizing matter-wave Fabry-Pérot interferometers for enhanced inertial sensing applications. Our study explores such tunneling-based sensors for the me…
