Breaching the horizons: Universal spreading laws confirmed

eurekalert.org – By extending the computational horizons from one day to the unprecedented time scales, the IBS researchers were able to confirm that a cloud of quantum particles continue to spread even when particle to particle interactions originally deemed to be the activator of the spreading, exert almost no strength. Their findings are published online in Jan. 30, 2019, in Physical Review Letters.
