Park, Hyunggyu
QUC Distinguished Professor
Statistical Physics
Hyunggyu Park has a broad experience in investigating emergent properties of general many body systems, ranging from classical magnetic systems, incommensurate systems, and quasicrystals to nonequilibrium stochastic complex systems. During the last decades, he focused on nonequilibrium phase transitions and critical phenomena and introduced several important concepts on how the system evolves into frozen states. Systems with frozen states show extensive applications from self-organized criticality to glassy systems with multiply degenerated ground states. Current interests include nonequilibrium fluctuation theorems, disordered systems, synchronization, ratchets, traffic flow, and networks.
