Phonon

Caption

First, a phonon is prepared at the location of ion 2 with an illuminating light. The vibration propagates among the four ions because of the Coulomb interaction between them. After a certain time (which varied between 0 to 0.01 seconds), the probability of finding the phonon at each ion was measured with another beam of light. The probability shows a complex pattern, which matches precisely with theoretical expectations.
