Yoseob Yoon is an assisant professor in the Department of Mechanical and Industrial Engineering and an affiliate faculty member in the Department of Physics.
Professor Yoon is an experimental condensed matter and quantum physicist specializing in the ultrafast coherent control and spectroscopy of low-dimensional quantum materials. His research focuses on inducing strong electronic and excitonic correlations through engineered van der Waals heterostructures (e.g., tunable moiré superlattices or interlayer coupling), strong external THz fields, and optical/THz cavities. He aims to elucidate how light-matter and matter-matter interactions give rise to emergent optoelectronic and quantum-mechanical properties, striving to achieve quantum control of material properties via enhanced interactions. To accomplish this, he employs a variety of spectroscopic techniques spanning visible to THz frequencies to monitor ultrafast dynamics, interactions, and transport of quasiparticles—such as moiré excitons, phonons, magnons, polarons, and polaritons—in quantum materials. His ultimate goal is to pave the way for the development of fast and efficient optoelectronic and quantum photonic devices.
