Self-trapped polarons and topological defects in a topological Mott insulatorCopyright: Markus Müller
In a recent article published in Physical Review Letters and highlighted as an Editor’s suggestion, a collaboration of researchers Sergi Julià-Farré, Maciej Lewenstein and Alexandre Dauphin from the Institute of Photonic Sciences (ICFO) with Markus Müller from RWTH Aachen University and Forschungszentrum Jülich, reports how an interplay between spontaneous symmetry breaking and global topological properties can lead to new strongly-correlated topological effects, which could be observed in systems of cold laser-excited Rydberg atoms. We invite you to also have a look at the summary of our work.

Welcome Eliana FiorelliCopyright: Eliana Fiorelli
Eliana realised her PhD at the University of Nottingham, UK, where she investigated signatures of associative memory in open quantum systems. At Aachen she is joining the ERC Starting Grant project QNets. She plans to bring in her expertise in quantum generalisations of classical neural networks and driven-dissipative open many-body quantum systems, to contribute to the development quantum neural networks in open atomic quantum systems.
Eliana started her work from 05th October 2020.
Lecture on Spatially Correlated Quantum DynamicsCopyright: Markus Müller
Markus Müller is grateful to have given a lecture on "Quantifying Spatial Correlations in General Quantum Dynamics" at this years virtual Autumn School on Correlated Electrons Topology, Entanglement, and Strong Correlations. Feel free to have a look at the presentation and lecture notes.
New method prevents quantum computers from crashingCopyright: Harald Ritsch
Quantum information is fragile, which is why quantum computers must be able to correct errors. But what if whole qubits are lost? In collaboration with colleagues at the University of Innsbruck and University of Bologna, we developed and experimentally implemented a method published in the journal Nature that allows quantum computers to keep going even if they lose some qubits along the way. We invite you to also have a look at the press release!
