The first is an activity that lets you build a carbon atom out of quarks and electrons. The second allows you manipulate a diamond crystal, giving you a three-dimensional look into how its carbon ...

In a single atom, photons can be absorbed and re-emitted ... Figure 1: Raman shift and diamond Raman laser design. In many materials operating at elevated temperatures, the one-phonon state ...

Their method used ultrafast laser pulses to knock some of a diamond’s carbon atoms out of place, leaving behind empty single-atom spaces that each exhibited a stable brightness level.
