International group of physicists including specialists from Landau Institute for Theoretical Physics improved their model describing damage processes in ruthenium thin films induced by powerful femtosecond laser. Such films are used as coatings for the mirrors of the European X-Ray Free-Electron Laser Facility (XFEL). This is a unique device that helps scientists to map atomic details of viruses, make snapshots of chemical reactions and even make “videos” of them. Understanding what happens when powerful laser pulse interacts with thin films, scientists can create more long-lasting covers for XFEL mirrors. Article is published in Applied Surface Science journal.
Theory developed by physicists from ITP will extend operational life of XFEL mirrors
Abrikosov vortices help scientists to explain inconsistencies in ‘dirty’ superconductors theory
International team of physicists including scientists from University of Grenoble, Landau Institute for Theoretical Physics, Weizmann Institute of Sciences and University of Utah explained anomalous low temperature behavior of ‘dirty’ superconductors. These materials possess various non-trivial properties which make them necessary part of quantum computers with superconductive qubits. In a paper published in Nature Physics, scientists report how ‘dirty’ superconductors can violate the conventional theory of superconductivity. With these results, it becomes possible to engineer superconductive qubits that are perfectly isolated from the outer disturbances and thus can be fully used for quantum computing.
