Open systems

    Measuring the escape of particles through the boundaries of the system is often a fruitful approach to understanding the dynamics. Examples include fractal basin boundaries in relativistic systems, fractal conductance fluctuations in semiconductor billiards, the effects of stochastic perturbations on the escape rate, and connections with number theory in escape from integrable systems including microresonators.

    Recent work has focused on billiards, with some surprising results: in the simplest possible geometry, the integrable circle, the escape is related to the Riemann Hypothesis. An intermittent system, the stadium billiard, exhibits asymmetric transport, with the time-dependence of the probability of remaining in the system being exponential (rapid) or algebraic (slow) depending on the holes through which the particle passes. This shows that open systems can behave very differently to their closed counterparts, and also leads to some interesting questions in the corresponding quantum/wave problems.
