Research Highlights from 2016-2018

Title, Journal: Jahn-Teller Effect in Systems with Strong On-Site Spin-Orbit Coupling, Physical Review Letters What?: When strong spin-orbit coupling removes orbital degeneracy, it would at the same time appear to render the Jahn-Teller mechanism ineffective; such a situation is discussed, Who?: IQST Fellow M. Daghofer  Read more
Title, Journal: Real-Time Dynamics in U(1) Lattice Gauge Theories with Tensor Networks, Physical Review X, What?: This work exploits recent algorithmic developments in the field of gauge-invariant tensor networks to investigate the real-time dynamics of string breaking in a quantum link formulation of the one-dimensional U(1) lattice gauge theory. Who?: IQST Fellow S. Montangero Read more
Title, Journal: A Four-Coordinate Cobalt(II) Single Ion Magnet With Coercivity and a Very High Energy Barrier, Nature Communications. What?: A cobalt single molecule magnet, with a record breaking energy barrier towards relaxation of the magnetization, was discovered and the origin of its properties fully elucidated. Who?: IQST Fellow J. van Slageren  Read more
Title, Journal: Nuclear magnetic resonance detection and spectroscopy of single proteins using quantum logic, Science, What?: Quantum logic, to improve readout fidelity, and a surface treatment technique, to extend the spin coherence time of shallow NV centers, are used to demonstrate a sensitivity sufficient to perform magnetic spectroscopy of an individual protein, Who?: IQST PI L. McGuinness IQST Fellows F. Jelezko Read more
Title, Journal: Observing the Rosensweig instability of a quantum ferrofluid, Nature, What?: A quantum fluid of tiny magnets, dysprosium atoms, was created with the properties of gases, crystals and superfluids combined into a single unique state of matter.  Who?: IQST PI: I. Ferrier-Barbut, IQST Fellow T. Pfau Read more
