Renyi entropy for monodromy defects of higher derivative free fields on even-dimensional spheres
Abstract
Explicit polynomial forms for R\'enyi and entanglement entropies are given on even --dimensional spheres which possess a codimension--2 U(1) monodromy defect. Free scalar and Dirac fields are treated and higher-derivative propagation operators employed. The central charge, CT, is also calculated. Comparison with existing results is made and it is shown how these can be obtained from the values here.
