The universal laws governing the dynamics of interacting quantum particles are yet to be fully revealed to the scientific community. A team of researchers at the Center for Theoretical Physics of Complex Systems (PCS), within the Institute for Basic Science (IBS in Daejeon, South Korea) have proposed to use an innovative toolbox that enables them to obtain simulation data of equivalent to 60 years’ experimental time. By extending the computational horizons from one day to unprecedented time scales, the IBS researchers were able to confirm that a cloud of quantum particles continues to spread even when particle to particle interactions, originally deemed to be the activator of the spreading, exert almost no strength. Their findings were published online on 30 January 2019 at Physical Review Letters.
