- westurner 8y ago"Scar (physics)": https://en.wikipedia.org/wiki/Scar_(physics) https://en.wikipedia.org/wiki/Scar_(physics) > Scars are unexpected in the sense that stationary classical distributions at the same energy are completely uniform in space with no special concentrations along periodic orbits, and quantum chaos theory of energy spectra gave no hint of their existence
- selimthegrim 8y agoTime crystals generally require active driving of some sort. They have a periodic behavior the opposite of parametric oscillation. A key feature of most time crystals is their long ‘prethermalizing’ behavior which is to say that it behaves like it isn’t thermalized for some very long but finite time. Whether these scars decay similarly especially within this constrained SU(2) space Lukin has cooked up is still out.
