ViennaNo amount of energy makes a quantum system equilibrate faster.
Nature Physics published a proof of the Planckian limit, long suspected from superconductor experiments.
Paolo Abiuso’s team at the Austrian Academy of Sciences showed the limit depends on temperature, Planck’s constant and Boltzmann’s constant.
At extremely low temperatures, the energy gap between a system’s two lowest states sets the limit instead.
The team checked its equations only on a theoretical model of interacting particles, not a lab device.

- explains the Planckian limit as a universal speed bound on thermalization that holds no matter how strongly the system is driven
