Dr. English has published more than 40 peer-reviewed research articles exploring “the nonlinear dynamics of complex systems.” His research interests broadly fall within the field of nonlinear and statistical physics. In recent years, topics have included: Intrinsic Localized Modes in Nonlinear Lattices, Spontaneous Synchronization of Oscillator Arrays, Pattern Formation, Instability, Bifurcation, Symmetry Breaking, Self-Organization Solitons, Skyrmions, and Chimera states. He has studied (both experimentally and numerically) systems as varied as: nonlinear electrical transmission lines, chains of coupled pendula , networks of neuronal oscillators, spin lattices, and networks of electrical self-oscillators. In all of these systems, nonlinearity and lattice/network geometry play important roles, as they enable and guide processes of patterns formation. Broadly speaking, the aim is to experimentally characterize emergent patterns, study their onset and boundaries in parameter space, and to formulate mathematical models which allow a numerical and/or analytical exploration. Ideas from the field of dynamical systems (such as fixed points, stability, bifurcation, hysteresis, chaos) are essential in this endeavor. Other interests include the Calculus of Variations, magnetism and spin resonance, microwave spectroscopy, medical imagining techniques, and issues within the philosophy of science.

2021-2022 Academic Year

Spring 2022

PHYS 212 Intro Relativistic/Quant Phys
Completion of both PHYS 211 and PHYS 212 fulfills the WID Requirement.

PHYS 331 Thermodynamics & Stat Mechan
The basic laws of thermodynamics are derived from principles of statistical mechanics. Thus, the laws governing our macroscopic world are seen as fundamentally statistical in nature. Familiar quantities, like temperature and pressure, will be re-discovered, and new ones, like entropy and free energy, will be developed and applied to real-world problems in engineering, condensed-matter physics, and chemistry. We will conclude with an examination of phase transitions and quantum statistics. Prerequisite: 211 and 212 and 282. Offered every two years.
