wave packet

noun Physics

A group of superposed waves which together form a travelling localized disturbance, especially one described by Schrödinger’s equation and regarded as representing a particle.Experiments in the 1980s, however, showed that it was possible for the peak of a wave packet to arrive sooner than it would had it travelled at c....

And when they repeated the experiment without interactions between the atoms, they saw obvious evidence for spreading of the wave packet.
For example, the phase velocity of a wave packet is a pseudo process but the group velocity is a causal process; yet both licence reliable predictions.
