Ultracold Atoms Challenge Entropy, Resist Heating

Quick Summary

• scientists at the University of Innsbruck ran an experiment on ultra-cold caesium atoms.
• Atoms were cooled to near absolute zero and arranged into thousands of one-atom-thick tubes. They were then “kicked” repeatedly with laser pulses.
• Contrary to expectations, the atoms did not thermalise or heat up but instead maintained similar velocities as if “frozen” in a single quantum state.
• The phenomenon challenges conventional understanding, where added energy typically leads to randomised motion and thermalisation due to entropy.
• Existing theories suggest certain quantum interactions may lead to such non-heating behavior, although mathematical models are limited in scope for large groups of interacting particles.
• Physicist Robert Konik suggests this finding might pave the way for advancements in quantum technologies like long-lasting information storage or sensing systems.
