Weak-link to tunneling crossover in an atomic Josephson junction
Vijay Pal Singh, Erik Bernhart, Marvin Röhrle +3
We present a unified, quantitative description of transport across the crossover between hydrodynamic weak-link flow and tunneling-dominated Josephson dynamics in a three-dimension…
Observation of Shapiro steps in an ultracold atomic Josephson junction
Erik Bernhart, Marvin Röhrle, Vijay Pal Singh +3
The current-voltage characteristic of a driven superconducting Josephson junction displays discrete steps. This phenomenon, called the Shapiro steps, forms today's voltage standard…
Dynamic Hysteresis Across a Dissipative Multi-Mode Phase Transition
Marvin Röhrle, Jens Benary, Erik Bernhart +1
Dissipative phase transitions are characteristic features in open quantum systems. Key signatures are the dynamical switching between different states in the vicinity of the phase…
A Kapitza Pendulum for Ultracold Atoms
Jian Jiang, Erik Bernhart, Marvin Röhrle +4
We report on the experimental realization of a Kapitza pendulum for ultracold atoms. Using time-periodic attractive and repulsive Gaussian potentials, we create an effective trap f…
