Ultrabright and narrowband intra-fiber biphoton source at ultralow pump power
Alexander Bruns, Chia-Yu Hsu, Sergiy Stryzhenko +5
Nonclassical photon sources of high brightness are key components of quantum communication technologies. We here demonstrate the generation of narrowband, nonclassical photon pairs…
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…
Universality-of-clock-rates test using atom interferometry with scaling
Fabio Di Pumpo, Alexander Friedrich, Christian Ufrecht +1
Metric descriptions of gravitation, among them general relativity as today's established theory, are founded on assumptions summarized by the Einstein equivalence principle (EEP).…
Light-pulse atom interferometry with entangled atom-optical elements
Tobias Asano, Fabio Di Pumpo, Enno Giese
The analogs of optical elements in light-pulse atom interferometers are generated from the interaction of matter waves with light fields. As such, these fields possess quantum prop…
Light propagation and atom interferometry in gravity and dilaton fields
Fabio Di Pumpo, Alexander Friedrich, Andreas Geyer +2
Dark matter or violations of the Einstein equivalence principle influence the motion of atoms, their internal states as well as electromagnetic fields, thus causing a signature in…
