Electronic and Magnetic Excitations in Correlated and Topological Materials

This ​thesis reports a major breakthrough in discovering the superconducting mechanism in CeCoIn₅, the “hydrogen atom” among heavy fermion compounds. By developing a novel theoretical formalism, the study described herein succeeded in extracting the crucial missing element of superconducting pairing interaction from scanning tunneling spectroscopy experiments. This breakthrough provides a theoretical explanation for a series of puzzling experimental observations, demonstrating that strong m...
