Systems consisting of many small particles can be highly complex and chaotic – and yet some can still be described using simple theories. However, whether this also extends to the world of quantum physics has remained unclear. Researchers from Ludwig Maximilian University and the Max Planck Institute for Quantum Optics have now found indications that quantum many-body systems can be macroscopically described by simple diffusion equations with random noise. The results were recently published in Nature Physics.
