Investigating interaction, superposition, and entanglement of quantum states in strongly correlated and topological materials that carry charge, spin, lattice and orbital degrees of freedom provide a wealth of knowledge for quantum energy and information sciences. In this talk, I’ll present my recent work of single-crystalline superconductors that benefited from developments of both charge transport/spectroscopy experiment techniques and theoretical understandings. In specific, I’ll focus on (1) the emergence of superconductivity in the electron-doped copper-oxide high-transition-temperature superconductors; (2) discovery of a relationship among superconductivity, magnetism, and topological states in iron chalcogenides; and (3) a novel method to induce and control superconductivity in quantum crystals using Focused Ion Beam.
