Phases, instabilities and excitations in a two-component lattice model with photon-mediated interactions
Leon Carl, Rodrigo Rosa-Medina, Sebastian D. Huber +3
Engineering long-range interacting spin systems with ultra cold atoms offers the possibility to explore exotic magnetically ordered phases in strongly-correlated scenarios. Quantum…
Superfluid signatures in a dissipative quantum point contact
Meng-Zi Huang, Jeffrey Mohan, Anne-Maria Visuri +6
We measure superfluid transport of strongly interacting fermionic lithium atoms through a quantum point contact with local, spin-dependent particle loss. We observe that the charac…
Tunable Non-equilibrium Phase Transitions between Spatial and Temporal Order through Dissipation
Zhao Zhang, Davide Dreon, Tilman Esslinger +3
We propose an experiment with a driven quantum gas coupled to a dissipative optical cavity that realizes a novel kind of far-from-equilibrium phase transition between spatial and t…
Quantisation and its breakdown in a Hubbard-Thouless pump
Anne-Sophie Walter, Zijie Zhu, Marius Gächter +5
Geometric properties of waves and wave functions can explain the appearance of integer-valued observables throughout physics. For example, these 'topological' invariants describe t…
