Stephen W. Teitsworth
Associate Professor of Physics

Prof. Stephen W. Teitsworth's research centers on experimental, computational, and theoretical studies of deterministic and stochastic nonlinear electronic transport in nanoscale systems. Three particular areas of current interest are: 1) stochastic nonlinear electronic transport phenomena in semiconductor superlattices and tunnel diode arrays; 2) complex bifurcations associated with the deterministic dynamics of electronic transport in negative differential resistance systems; and 3) strategies for stabilizing negative differential resistance systems against the formation of space-charge waves.

Current Research Interests

  • Current research centers on experimental, theoretical and computational investigation of rare fluctuation processes in noise-driven nonlinear dynamical systems that are far from thermal equilibrium.  The experimental platforms for studying these phenomena are bistable electronic transport systems, principally semiconductor superlattices and tunnel diodes.  Theoretical work utilizes stochastic Lagrangian methods, while computational work focuses on the direct simulation of systems of nonlinear stochastic differential equations.
