High-temperature superconductors have emerged as a promising platform for generating coherent terahertz (THz) radiation through the intrinsic Josephson effect. Josephson junctions—formed at the ...
The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU University of Kaiserslautern-Landau have therefore implemented a quantum simulation ...
The research was published in the journal Science ("Observation of Shapiro steps in an ultracold atomic Josephson junction"). Two superconductors separated by a wafer-thin insulating layer – that's ...
Josephson junctions are quantum mechanical devices consisting of two superconductors separated by a thin insulating barrier. They are named after Brian Josephson, who predicted their unique properties ...
The experiment takes place in a vacuum chamber, where ultracold atomic clouds with a temperature of 30 nK are generated via laser cooling. Pictured: Professor Herwig Ott and Dr. Erik Bernhart. They ...
