  • Theory sorts order from chaos in complex quantum systems

    The graphic shows an orange and blue fractal image illustrating mathmatical order and chaos

    Classical chaos – or the butterfly effect – produces fractal patterns like the one shown. Classical chaos’s cousin – quantum information scrambling – encompasses even more exotic mechanisms such as quasiparticles hopping between molecules, which can dissipate energy.
