SUMMARY:CM Seminar- "Visualizing Unconventional Superconductivity with Superconductive Probes at the Atomic Scale" with Prof. Xiaolong Liu
DESCRIPTION:    Prof. Xiaolong Liu  Department of Physics and Astronomy  Stavropoulos Center for Complex Quantum Matter  University of Notre Dame, Notre Dame, IN    In most conventional superconductors, spin-singlet electron pairing results in a translationally invariant condensate with spatially uniform superfluid density. However, electron pairs can not only form crystalline states known as pair density waves (PDWs) by coupling with density wave orders, but also exist in a spin-triplet state. Furthermore, in multi-band superconductors, multiple superconducting condensates can coexist, raising the question of how these condensates are spatially arranged. In this talk, I will present our recent exploration of unconventional superconductivity using superconductive tips in sub-Kelvin scanning tunneling microscopes. I will start by showing the detection of composite PDWs in materials with dominant charge density waves and visualization of superfluid flow around vortices. Then, I will discuss signatures of non-chiral spin-triplet superconductivity, atomic-scale quantum interference, and multi-condensate visualization, all enabled by the use superconductive probes.     | Event post: https://phys.uic.edu/events?page_id=5665
