Superconductivity has been a central topic in condensed matter physics for over a century. Together with its fundamental interest, it offers a fertile ground for innovative technologies. The superconductivity group at the LAF works on both aspects: finding and tackling emergent physical problems as well as developing novel applications.
Much of our focus is on high-Tc superconducting systems. This choice is crucial for applications since devices based on those superconductors can operate at temperatures in the tens of K range, radically diminishing the burden of cryogenics both in terms of energy consumption and volume a formidable advantage compared to conventional low-TC superconductors. From the fundamental point of view, high-Tc superconductors constitute one of the major unsolved problems in condensed matter physics, and their d-wave pairing is an enriching ingredient in a variety of generic open problems from proximity effects to vortex physics and spin dynamics.
As we detail below, our activities in the area are organized in various research axes that span from quantum interference sensors and superconducting devices for information technologies, signal processing, computing, or medical imaging, to novel materials and superconducting hybrids.
