| Order parameters from persistent homology in non-Abelian gauge theory |
| Speaker: | Daniel Spitz (University Heidelberg) |
| Abstract: | Finding order parameters for the detection of critical phenomena and self-similar behavior in and out of equilibrium is a non-trivial endeavour in non-Abelian gauge theories. Tailored to detect topological structures in noisy data, recently both the sensitivity of persistent homology observables to equilibrium phase transitions as well as their suitability to describe far-from-equilibrium self-similar scaling have been demonstrated. In this talk I will provide an introduction to persistent homology, describe its application in SU(2) gauge theory in 3+1 dimensions, and use different filtrations by local energy densities or Polyakov loops computed from simulated field configurations to gauge-invariantly describe the confinement-deconfinement transition as well as reveal self-similar scaling in far-from-equilibrium scenarios. These results showcase the broad usability of persistent homology |
