Quantum Fields on Star Graphs with Bound States at the Vertex

Boz, Tamer Süleyman January 2011 (has links)
A star graph consists of an arbitrary number of segments that are joined at a point which is called the vertex. In this work it is investigated from a pure theoretical point of view, in the framework of quantum field theory. As a concrete physical application, the electric conductance tensor is obtained. In particular it is shown that this conductance behaves differently according to whether the scattering matrix associated with the vertex of the graph has bound-state poles or not.

Abelian Chern-Simons theory with toral gauge group, modular tensor categories, and group categories

Stirling, Spencer 06 September 2012 (has links)
Classical and quantum Chern-Simons with gauge group U(1)N were classified by Belov and Moore in [BM05]. They studied both ordinary topological quantum field theories as well as spin theories. On the other hand a correspondence is well known between ordinary (2 + 1)-dimensional TQFTs and modular tensor categories. We study group categories and extend them slightly to produce modular tensor categories that correspond to toral Chern-Simons. Group categories have been widely studied in other contexts in the literature [FK93],[Qui99],[JS93],[ENO05],[DGNO07]. The main result is a proof that the associated projective representation of the mapping class group is isomorphic to the one from toral Chern-Simons. We also remark on an algebraic theorem of Nikulin that is used in this paper. / text
