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. |
