These dragonfly-like patterns are chaotic and quasi-periodic states in a radio-physical oscillator system. In their recent JPhysA paper, Kuznetsov and colleagues have investigated where these dynamics appear in a system that doesn’t have an equilibrium point, where one wouldn’t naturally expect to find this type of behaviour.

In this Publisher’s Pick article, Paul Bressloff and Sean Lawley discuss their latest work in JPhysA, which uses the theory of stochastic hybrid systems to analyse a piecewise deterministic dynamical system and establish a deep connection with the Brownian motion of individual particles.
We interview Dorje Brody, newly appointed to the JPhysA Editorial Board, about his work on the boundaries of quantum mechanics, statistical mechanics and mathematical finance.
Christopher Ferrie and Richard Kueng get a chuckle for naming their preprint Have you been using the wrong estimator? These guys bound average fidelity using this one weird trick von Neumann didn’t want you to know. Sadly, the paper doesn’t contain 31 gifs of quantum states that prove you were a 90s kid.
