Wykład zatytułowany Planar Josephson junctions: platform for topological superconductivity wygłosi prof. dr hab. Tadeusz Domański z Uniwersytetu Marii Curie-Skłodowskiej w Lublinie.
Josephson effect, predicted over half a century ago and observed in numerous configurations, is one of the spectacular quantum mechanical signatures manifested on macroscopic scale. Its mechanism relies on superflow of the Cooper
pairs driven between the phase-differing superconducting samples. Constrained into a superconducting quantum interferometer device (SQUID) it allows for ultra-precise detection of the magnetic fields, induced e.g. by tiny neural currents
in a human body. New recent interests in the Josephson-type planar junctions are motivated by the phase-tunable engineering of the topologically nontrivial superconducting stripes, harboring the Majorana boundary modes. I shall
overview experimental status and discuss promising perspectives of this platform.
