# Lattice QCD - Topological objects

First results of a pilot project with QCD lattice data.

For this soniﬁcation, the topological charge density,
given by one real number per lattice site, served as data. Our research
question was, whether local topological structures could be found in the
data, e.g. instantons, which are hidden under random
quantum ﬂuctuations. The soniﬁcation challenge was to display complex
data locally in a 4d structure and allow some orientation. As the data
are very large, we utilize ‘sub-hypercubes’, small
regions around a chosen site. We have implemented two soniﬁcation
approaches: a ‘resonated audiﬁcation’ and ‘dynamical
resonators’. They are similar in concept, as both excite
resonator frequencies with a signal, but the roles of excitator and
resonator are reversed. |
