When disruptions become usefulQuantum noise tamed in the tunnel effect
What is usually considered a disturbance can be surprisingly useful under certain conditions: noise. Researchers at the University of Duisburg-Essen have shown how the random noise caused by the quantum mechanical tunnel effect - a phenomenon that is also the focus of this year's Nobel Prize in Physics - can be specifically influenced. The results, which have now been published in Communications Physics, open up new perspectives for future quantum devices.
Researchers create conductive interface in nickelate materialsLight switch for electrons
UV light can be used to switch an extremely conductive state on and off at the interface between two oxide materials - in a matter of seconds. This newly discovered "light switch for electrons" marks a milestone on the way to light-controlled electronics and could also be used in superconductivity in the future. The journal Nature Materials reports. Part of the international team are CENIDE member Prof. Dr. Rossitza Pentcheva (University of Duisburg-Essen) and her former colleague Dr. Benjamin Geisler (University of Florida).
Maglev train experiment in the final of "Die beste Klasse Deutschlands"Floating superconductor: research collaboration shows levitation in KiKa
As part of their work in the Collaborative Research Center/Transregio (CRC/TRR), researchers from the University of Duisburg-Essen have brought high-tech research to the "superfinals" of the popular KiKA show "Die beste Klasse Deutschlands". For the show, on October 11, 2025 (from minute 24:25), Dr. Nicolas Josten from CENIDE member Professor Michael Farle's working group traveled to Erfurt to support the production with a special experiment.
