Optimal squeezing for high-precision atom interferometers
Polina Feldmann, Fabian Anders, Alexander Idel +5
We show that squeezing is a crucial resource for interferometers based on the spatial separation of ultra-cold interacting matter. Atomic interactions lead to a general limitation…
Excited-State Phase Diagram of a Ferromagnetic Quantum Gas
Bernd Meyer-Hoppe, Fabian Anders, Polina Feldmann +2
The ground-state phases of a quantum many-body system are characterized by an order parameter, which changes abruptly at quantum phase transitions when an external control paramete…
Momentum Entanglement for Atom Interferometry
F. Anders, A. Idel, P. Feldmann +13
Compared to light interferometers, the flux in cold-atom interferometers is low and the associated shot noise large. Sensitivities beyond these limitations require the preparation…
Dynamical low-noise microwave source for cold-atom experiments
Bernd Meyer-Hoppe, Maximilian Baron, Christophe Cassens +4
The generation and manipulation of ultracold atomic ensembles in the quantum regime require the application of dynamically controllable microwave fields with ultra-low noise perfor…
Phase magnification by two-axis countertwisting for detection noise robust interferometry
Fabian Anders, Luca Pezzè, Augusto Smerzi +1
Entanglement-enhanced atom interferometry has the potential of surpassing the standard quantum limit and eventually reaching the ultimate Heisenberg bound. The experimental progres…
