Superconductivity is the ability of an electronic material to conduct electrical current without resistance. This property underpins many existing and proposed technological applications, ranging from medical imaging to low-energy electronics and quantum computing. In this project, we aim to demonstrate a highly unconventional route towards superconductivity at room temperature and atmospheric pressure, by exploiting collective behaviour of excitons (electron-hole pairs in a semiconductor) strongly coupled to photons. This research should help to overcome the biggest challenge for the widespread applications of superconductors: the very low temperature or extreme pressure that the superconducting materials need to function.Read moreRead less

This burgeoning research field, however, suffers from the same limitations of all spintronic concepts – the high currents needed to move skyrmions. Magnonics is yet another emerging approach, which main aim is to investigate the behaviour of spin waves in magnetic nanostructures.
