We are looking for highly motivated undergraduate and graduate research assistants! If you are interested, please feel free to contact Professor Lee at minhyea.lee[at]colorado.edu
Research
My group studies quantum materials — crystalline solids with unusual physical properties arising from the quantum mechanical nature and interactions of electrons. Our interests include exotic magnetic phases and their low energy excitations, heat transport mechanisms, strong spin-orbit interaction, and its imprints on light-matter interactions. These topics are not only at the heart of exciting developments in quantum materials research but also have strong potential to play a vital role in future technologies.
We are particularly interested in magnetic materials: Advances in spintronics and quantum information processing are firmly rooted in understanding not only the properties of magnetically ordered states, spin excitations, and exotic ground states but also of the nature of the interaction between spin and lattice degrees of freedom.
My group employs a range of experimental probes -- transport properties, Magneto-Optical Spectroscopy, Cantilever-Based Magnetometry, and various Thermodynamic Variable measurements under intense magnetic fields, high pressure and low temperature, to investigate the ground states and their low-energy excitations as well as the fundamental nature of couplings among different degrees of freedoms within crystalline solids
