Dr. Michał Tomza from the Institute of Theoretical Physics of the Faculty of Physics of the University of Warsaw, together with Dariusz Wiater, a PhD student of this faculty, and researchers from the University of Amsterdam, were the first to carry out time ultra-cold collisions in the quantum regime between a single ion and atoms. The results of their work were published in Nature Physics.
A new experiment that will investigate the properties of the lightest particles of matter, known as neutrinos, has been approved by the European Organization for Nuclear Research (CERN). Dr. Sebastian Trojanowski from the National Centre for Nuclear Research (NCBJ) played an important role in the project.
Even faster processors with even smaller dimensions? Wherever neither electronics nor spintronics can cope with performance or miniaturization, magnonics comes to the rescue. But before that happens, scientists must learn how to accurately simulate the flow of magnetic waves through magnonic crystals. At the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow an important step in this direction has just been made.
Almost everyone uses nanometer-sized alumina these days – this mineral, among others, constitutes the skeleton of modern catalytic converters in cars. Until now, the practical production of nanocorundum with a sufficiently high porosity has not been possible. The situation has changed radically with the presentation of a new method of nanocorundum production, developed as part of a German- Polish cooperation of scientists from Mülheim an der Ruhr and Cracow.
If it were possible to observe neutrinoless double beta decay, it would be tantamount to the discovery of a new elementary particle - a Majorana-type particle. Such a finding would be as momentous as the discovery of the Higgs boson. Researchers are getting closer to this discovery, as reported in Science.
Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide as an example, physicists from Cracow and Warsaw have shown that even such computationally demanding defects can be successfully examined with atomic accuracy by means of a cleverly constructed, small in size, model.
