Measurements of Superconducting Quantum Materials and Superconductor Devices
Explore phase-sensitive measurements of exotic superconducting quantum materials and hybrid superconductor devices in this 31-minute conference talk by Dale Van Harlingen from the University of Illinois at Urbana-Champaign. Delve into the power of Josephson interferometry as a probe for phase anisotropy in unconventional superconductors and coherent states in hybrid devices. Learn about the technique's applications, from determining order parameter symmetry in high-temperature cuprate superconductors to investigating materials with multiple superconducting states, complex order parameters, and topological properties. Discover related methods for measuring current-phase relations in Josephson devices and their use in studying supercurrent transport, the interplay of superconductivity and magnetism, and the search for exotic excitations like Majorana fermion states in topological superconductor devices, with potential implications for topologically-protected quantum computing.
