Plate 4: This is a typical pattern of activity in the gluon fields of QCD. Such activity patterns lie at the heart of our successful computation of hadron masses, as discussed in Chapter 9, so we can be confident that they correspond to reality.
This beautiful image is a still from "Lava Lamp" one of many QCD vacuum animations computed by Derek Leinweber, CSSM, University of Adelaide.
Leinweber describes the QCD "Lava Lamp" as an "Animation of the Action Density in 4 Dimensions...It is an excellent animation of the 4 dimensional structure of the long-distance aspects of the QCD vacuum."
Leinweber acknowledges help on creating his animations as follows: "My thanks to John Ahern, Frederic Bonnet, Sundance Bilson-Thompson, Patrick Fitzhenry, Greg Kilcup, Mark Stanford and Tony Williams for their contributions to making these images possible. Additional thanks to Francis Vaughan of the SACPC for generous supercomputer support and the DHPC Group for support in the development of parallel algorithms."
