The modeling of chaotic phenomena has provided many colorful images, but only rarely has it captured the unusual physical behavior found in the realm of quantum mechanics. The cover image is a Poincaré section, or a stroboscopic snapshot, of a chaotic attractor describing the motion of electrons in a system that couples components from the classical and quantum (here, the superconducting) domains—an example of "semiquantum chaos." This work by the Quantum Circuits Research Group at the University of Sussex in the U.K. is discussed by Mason A. Porter and Richard L. Liboffin in "Chaos on the Quantum Scale."
