High Pressure Synthesis of New Superconductors (Minu Kim)

The field of condensed matter physics has made a great leap forward with the discovery of high transition temperature (Tc) superconductivity in the layered cuprates, iron pnictides, and more recently, pressurized metal hydrides and infinite-layer nickelates. While physical properties of superconductors have offered text-book examples of quantum mechanics, the microscopic underlying mechanism of superconductivity in some recently discovered compounds has still remained to be clarified. Development of new superconductors is a key quest to understand complex quantum phenomena intertwined with superconductivity and eventually make a breakthrough in the current understanding of superconductivity.

In this project, a candidate will make new superconductors using a high-pressure high-temperature synthesis technique. A candidate will learn basic concepts in materials design, crystal growth, as well as characterization of a crystal. In particular, high-pressure apparatus provide a unique opportunity for us to artificially stabilize new materials under extreme conditions, which do not exist at atmospheric pressure [1,2]. A new compound made by a candidate will be subject to further investigation within the MPI-UBC-UTokyo collaborations using state-of-art measurement techniques, providing possible options of graduate studies in the institutes.
