Abstract

Non-technical Abstract: Achieving superconductivity under an ambience environment is one of the holy grails in physics because it would drastically improve energy efficiency by eliminating energy loss due to resistance. This project builds upon the complementary expertise of two scientists to identify signatures of superconducting pairing symmetries. The team aims to shed light on how various symmetries govern the onset of superconductivity in different classes of superconductors using a nonlinear optical measurement method called second harmonic generation. This technique is highly sensitive to symmetry changes in crystalline materials. Combined with other electronic and magnetic property measurements, the scientists can provide insights and guidance on how to potentially custom design materials capable of hosting superconductivity under less cold conditions. The research team is dedicated to attracting and engaging young minds to the field of physics through expanding outreach activities. The collaborative research offers necessary education for preparing undergraduate and graduate students for the next quantum technology revolution and the needed workforce for economic growth in South Carolina. Technical abstract: This research project is designed to experimentally investigate the bulk and surface physical properties of unconventional superconductors to expose new phases, especially broken symmetries. This project builds upon the complementary expertise of two scientis
