CambridgeHarvard physicists find isolated quantum systems retain traces of their start.
Classically, chaos erases a system’s starting conditions, so an ergodic system should forget how it began.
In Physical Review X, the team reports scrambled states still revisit their own history more often than random ones.
Senior author Joonas Keski-Rahkonen says the effect is far more general than quantum scars, where single states defy ergodicity.
