Single-atom billiards in an ultracold bath with energy-tunable collisions and threshold-sensitive detection

Silvia Hiebel, Sabrina Burgardt, Julian Feß +1

Transport processes at the microscopic scale can differ strongly from their macroscopic counterparts, particularly when the environment is not a well-defined surface but an unorder…

Enhancing the power of a quantum heat engine via control of the system--reservoir coupling

Sabrina Burgardt, Julian Feß, Silvia Hiebel +2

The non-equilibrium properties of open quantum systems are determined by the microscopic laws governing energy exchange with their environment. In particular, an enhancement of the…

Quantum-enabled active matter at the atomic scale

Sabrina Burgardt, Julian Feß, Alexander Guthmann +8

Active matter comprises particles that extract energy from their local environment and convert it into motion. Although active particles have been miniaturized down to the nanoscal…

Characterizing quantum gases in time-controlled disorder realizations using cross-correlations of density distributions

Silvia Hiebel, Benjamin Nagler, Sian Barbosa +2

The role of disorder on physical systems has been widely studied in the macroscopic and microscopic world. While static disorder is well understood in many cases, the impact of tim…

Measuring the environment of a Cs qubit with dynamical decoupling sequences

Sabrina Burgardt, Simon B. Jäger, Julian Feß +3

We report the experimental implementation of dynamical decoupling on a small, non-interacting ensemble of up to 25 optically trapped, neutral Cs atoms. The qubit consists of the tw…

Indication of critical scaling in time during the relaxation of an open quantum system

Ling-Na Wu, Jens Nettersheim, Julian Feß +6

Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields. Near continuous phase tr…

Ultracold Bose gases in disorder potentials with spatiotemporal dynamics

Benjamin Nagler, Martin Will, Silvia Hiebel +4

We study experimentally the dissipative dynamics of ultracold bosonic gases in a dynamic disorder potential with tunable correlation time. First, we measure the heating rate of the…
