Relaxation dynamics of an isolated large-spin Fermi gas far from equilibrium
Ulrich Ebling, Jasper Simon Krauser, Nick Fläschner +4
A fundamental question in many-body physics is how closed quantum systems reach equilibrium. We address this question experimentally and theoretically in an ultracold large-spin Fe…
Translationally invariant multipartite Bell inequalities involving only two-body correlators
J. Tura, A. B. Sainz, T. Vértesi +3
Bell inequalities are natural tools that allow one to certify the presence of nonlocality in quantum systems. The known constructions of multipartite Bell inequalities contain, how…
Observation of Topological Structures in Photonic Quantum Walks
Graciana Puentes, Ilja Gerhardt, Fabian Katzschmann +3
Phases of matter with non-trivial topological order are predicted to exhibit a variety of exotic phenomena, such as the existence robust localized bound states in 1D systems, and e…
Quantum Hall phases of two-component bosons
Tobias Graß, David Raventós, Maciej Lewenstein +1
The recent production of synthetic magnetic fields acting on electroneutral particles, like atoms or photons, has boosted the interest in the quantum Hall physics of bosons. Adding…
Topological phases in small quantum Hall samples
Tobias Graß, Bruno Juliá-Díaz, Maciej Lewenstein
Topological order has proven a useful concept to describe quantum phase transitions which are not captured by the Ginzburg-Landau type of symmetry-breaking order. However, lacking…
Many body population trapping in ultracold dipolar gases
O. Dutta, M. Lewenstein, J. Zakrzewski
A system of interacting dipoles is of paramount importance for understanding of many-body physics. The interaction between dipoles is {\it anisotropic} and {\it long-range}. While…
