Researcher from the Institute of Physics of Slovak Academy of Sciences - Dr. Denis Kochan - participated at exciting discovery reported recently in highly impacted journal Nature Nanotechnology (impact factor 40.523). Jointly with physics research teams of Professor Christoph Strunk and Professor Jaroslav Fabian (both from University of Regensburg in Germany) they have demonstrated both experimentally and theoretically a dramatic change in sign of the supercurrent diode effect. Superconducting diodes, first designed in 2021 and also known as Josephson diodes, serve as the basic building blocks for new types of superconducting circuits that may replace the resistive ones in the future. The discovery will have major implications in the field of superconductivity and superconducting spintronics and boost further the development of quantum electronics and quantum technologies. Denis Kochan is the holder of the prestigous Slovak Academy of Sciences grant IMPULZ (IM-2021-26) focused on theoretical development and understanding of the physics of superconducting spintronics.
