Yoshitsugu Oono
Professor of Physics
Professor Oono received his Ph.D. in physics and chemistry from Kyushu University in Japan in 1976. After serving as an assistant professor in the Research Institute of Industrial Science at Kyushu University, he joined the physics faculty at the University of Illinois in 1981.
Professor Oono is an internationally recognized leader in theoretical physics, whose seminal research has contributed to understanding many problems in "soft" physics, i.e. the physics of complicated systems, such as polymers and porous media. He has formulated important insights in three distinct areas-the theory of chaos, nonequilibrium statistical thermodynamics, and the dynamics of polymers. His work is characterized by the novel use of ideas and techniques from a variety of subdisciplines of physics, an attention to and mastery of detail, and a constant endeavor to relate his theoretical studies to experiment.
Research Areas: statistical physics in the broadest sense (nonequilibrium, including biological, hydrodynamical, and dynamical systems), applied mathemathics
Description of Current Research
Studies of Nonlinear Dynamics
The group does various research projects in nonlinear dynamics. The research projects include (1) the formation and dynamics of spatial patterns, (2) Hamiltonian systems with few degrees of freedom, (3) dynamic cell models, and (4) almost periodic and quasiperiodic systems.
Equilibrium and Nonequilibrium Phenomena in Condensed Matter
We are modeling phase transition kinetics, developing large deviation and fluctuations theories for nonequilibrium systems, and studying dynamic scaling in high-temperature superconductors. Ongoing projects include numerical renormalization group methods for PDEs and critical scaling in black hole formation.
