      abstract     = {This study comprises an ab-initio computational
                      investigation of the topological Hall effect (THE) arising
                      from magnetic skyrmions in thin film Pd/Fe/Ir(111)[1]. The
                      research is motivated by the significance of electrically
                      detecting magnetic skyrmions for spintronic applications. To
                      achieve the formation of stable magnetic skyrmions in this
                      system, we employ non-collinear spin-density-functional
                      theory within the Korringa-Kohn-Rostoker (KKR) Green
                      function method. The multiple scattering problem is solved
                      using the full-potential relativistic KKR method [2], and
                      subsequently, the spin-transport calculations are carried
                      out using the Boltzmann formalism [3] to find the
                      resistivity and the topological Hall angle. We investigate
                      the influence of the skyrmion size on the Hall angle and
                      explore the impact of additional electron scattering,
                      modeled as random disorder broadening, on the THE. Our
                      findings indicate a significant correlation between the THE
                      and the degree of disorder in a sample.We thank the ML4Q
