Research Interests
We are experimental condensed matter physics group at department of physics in UNIST (Ulsan National Institute of Science and Technology). Our main goal is searching for exotic quantum phenomena in condensed matter, such as chiral superconductivity, topological phases, and quantum magnetism, as well as providing new functional materials, i.e. multiferroics and energy materials, for future applications. To accomplish our goals, we are synthesizing new quantum materials unobtainable in nature and controlling their ground states via Hamiltonian engineering.
