  • Researchers derive a unified topological speed limit for the evolution of physical states

    Updated: 2023-01-24 15:06:57
    Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods for determining the speed at which physical systems change over time, however, do not account for these structural properties.
