We give a description of the delocalized twisted cohomology of an orbifold and the Chern character of a twisted vector bundle in terms of supersymmetric Euclidean field theories. This includes the construction of a twist functor for \({1\vert1}\)-dimensional EFTs from the data of a gerbe with connection.



Open access funding provided by Max Planck Society. This paper is based on a part of my Ph.D. thesis [24], and I would like to thank my advisor, Stephan Stolz, for the guidance. I would also like to thank Matthias Ludewig, Byungdo Park, Peter Teichner, and Peter Ulrickson for valuable discussions, and Karsten Grove for the financial support during my last semester as a graduate student (NSF Grant DMS-1209387).
