“Superconductors investigated by high-energy particle irradiations” by Kyuil Cho, PhD, Assistant Professor, Physics Department Abstract: Superconductor is a material that shows zero resistivity and Meissner effect below its critical temperature. This material has been used for various applications such as superconducting wires, medical device MRI, superconducting magnets for particle accelerator, quantum computing circuits, and many more. Recent discovery of a room temperature superconductor [1] attracts much more attention to the field of superconductivity. The superconductivity research group at Hope College conducts a unique research to study the fundamental mechanism of newly discovered superconductors by using high energy particles. The high energy particle is a useful tool to generate impurities on novel superconductors. By investigating how the impurities affect the properties of superconductors, one can uncover the fundamental mechanism of superconductivity. In this talk, I will present an interesting physics discovered in NbSe2 superconductor using high energy particle irradiations [2]. [1] E. Snider et al., Nature 586, 373 (2020). [2] K.
