Josephson spectroscopy in a circular atomic tunnel junction with acceleration-induced symmetry breaking
Yurii Borysenko, Yuriy Bidasyuk, Olena Prykhodko +5
We study Josephson dynamics in a long atomic Bose-Josephson junction formed by two tunnel-coupled coplanar Bose-Einstein-condensate rings. An in-plane linear acceleration breaks th…
Dynamics of repeated BEC formation and extraction in dimple traps
Kyrylo Kovalchuk, Dominik Pfeiffer, Ludwig Lind +3
We investigate repeated Bose-Einstein-condensate (BEC) formation and extraction in a dimple trap embedded in a reservoir of thermal atoms using a kinetic model. The model includes…
Parameter Estimation from Amplitude Collapse in Correlated Matter-Wave Interference
Daniel Derr, Dominik Pfeiffer, Ludwig Lind +2
Operating matter-wave interferometers as quantum detectors for fundamental physics or inertial sensors with unprecedented accuracies relies on noise rejection, often implemented by…
Dichroic mirror pulses for optimized higher-order atomic Bragg diffraction
Dominik Pfeiffer, Maximilian Dietrich, Patrik Schach +2
Increasing the sensitivity of light-pulse atom interferometers progressively relies on large-momentum transfer techniques. Precise control of such methods is imperative to exploit…
