Abstract: We introduce a contagion-like opinion model that includes dynamic resistance to alternative opinions. We show that this model can describe candidate vote distributions, spatial vote correlations, and slow opinion consensus with sensible parameter values. This may suggest that all these distinct behaviors, previously understood using distinct models, may in fact be different aspects of a unified description of human behavior, described by our new model.

Abstract: Humans interact with chaotic systems on everyday basis. Chaos plays a fundamental role on a wide span of length and time scales. Since it is hard to isolate a chaotic system from random interactions with the environment, the challenges in studying its behavior are both mathematical and experimental. In recent years, atomic gasses have emerged as experimentally accessible systems for observing chaos under controlled conditions. In this talk I will present the study of geometric structures in phase space that govern the chaotic transport in an atomic system. I will show how these results apply to understanding the chaotic ionization in Rydberg atoms. Theoretical results are based on the study of a homoclinic tangle and its corresponding turnstile. Understanding the relationship between the turnstile and the system parameters allows us to draw conclusions about the ionization process and to design the experiments for probing the structure of the chaotic phase space. Finally, I will present a set of recent results which show that this approach can be used to design an experimental protocol for nonadiabatic energy change of an electron ensemble.

Abstract: It is well established that certain fluid flows with no growing linear eigenmodes can still support turbulence. Here we discuss a related phenomenon in a plasma, related to drift waves driven by a density gradient. The hydrodynamic and plasma problems are different in that sheared equilibrium flow is not needed in the latter case, and the shearing of the magnetic field plays a role like viscosity. As in the hydrodynamic case, in the plasma problem there can be substantial transient linear growth before exponential decay. Generalizing an argument from hydrodynamics, we can prove that such transient linear growth is necessary for sustained nonlinear turbulence.
