Interferometric Unruh detectors for Bose-Einstein condensates
Cisco Gooding, Steffen Biermann, Sebastian Erne +4
The Unruh effect predicts a thermal response for an accelerated detector moving through the vacuum. Here we propose an interferometric scheme to observe an analogue of the circular…
From the moving piston to the dynamical Casimir effect: explorations with shaken condensates
Marios H. Michael, Joerg Schmiedmayer, Eugene Demler
Recent experimental realizations of uniform confining potentials for ultracold atoms make it possible to create quantum acoustic resonators and explore nonequilibrium dynamics of q…
One-dimensional atomic superfluids as a model system for quantum thermodynamics
Joerg Schmiedmayer
In this chapter we will present the one-dimensional (1d) quantum degenerate Bose gas (1d superfluid) as a testbed to experimentally illustrate some of the key aspects of quantum th…
Uncover Topology by Quantum Quench Dynamics
Wei Sun, Chang-Rui Yi, Bao-Zong Wang +9
Topological quantum states are characterized by nonlocal invariants, and their detection is intrinsically challenging. Various strategies have been developed to study topological H…
Solid-state electron spin lifetime limited by phononic vacuum modes
Thomas Astner, Johannes Gugler, Andreas Angerer +10
Longitudinal relaxation is the process by which an excited spin ensemble decays into its thermal equilibrium with the environment. In solid-state spin systems relaxation into the p…
Local emergence of thermal correlations in an isolated quantum many-body system
Tim Langen, Remi Geiger, Maximilian Kuhnert +2
We experimentally demonstrate how thermal properties in an non-equilibrium quantum many- body system emerge locally, spread in space and time, and finally lead to the globally rela…
