Explore the fascinating world of nanoscale electronics and spintronics in this 58-minute lecture by Mats Jonson from PCS Institute for Basic Science. Delve into the concept of controlling electron charge and spin flow in BCS superconductors. Discover how the typically "locked" spin-singlet state of Cooper-paired electrons can potentially be "unlocked" for spintronics applications. Examine the process of spin-dependent electron tunneling through voltage-biased micro-constrictions between bulk superconductors. Learn about the creation of static magnetization near constrictions and the generation of ac Josephson-like spin currents. Consider the implications of these findings for the development of electrically controlled, dissipation-less spintronics technologies.
