Cheering up a frustrated quantum system

One of the holy-grail questions in condensed matter physics is how superconductivity — the property of many electrons to go into a quantum soup state that can carry electricity without losses — emerges at relatively high temperatures in certain materials, and how these temperatures could be boosted even further. Now a research team at the University of Oxford and the MPSD is reporting in Physical Review Letters that a dynamical version of superconductivity, which is generated by periodically shaking the material, is intimately tied to strong electronic correlations and geometric frustration.

Riku receives Academy of Finland funding

Riku Tuovinen has been granted an Academy of Finland 3-year independent funding award starting in September 2019. In his project “Ultrafast many-body correlations in quantum transport and spectroscopy” Riku will develop and apply novel theoretical and computational methods for many-body quantum phenomena out of equilibrium. Congratulations, Riku!

Gabriel’s paper is out in Nature Communications: G. E. Topp et al., Nature Communications 9, 4452 (2018). Here is a link to the press release “Shedding light on Weyl fermions” on the MPSD website (click here for a German version).

Congratulations, Gabriel!
