Research: In his early work, Swift used the mode-mode coupling formalism to investigate dynamical critical phenomena. The first quantitative predictions of the singular behavior of the thermal conductivity and diffusion constant near critical points were the results of this work. In a long term effort, he and collaborators then studied the thermodynamic, structural, viscous, and hydrodynamic properties of numerous phases of liquid crystals. Swift's research then focused on the theoretical investigation of instabilities, pattern formation, and chaos in nonequilibrium, nonlinear systems. Results include (a) the development of a simplified field model which has been widely used to study patterns, instabilities, wavelength selections, onset, and the effects of thermal noise in convecting systems and (b) the development of methods, particularly the spectrum of Lyapunov exponents, for characterizing the complex behavior of systems exhibiting chaos. His research now concerns the rapid flows of granular materials. Affiliations: Center for Nonlinear Dynamics Department of Physics |
