Line Operators of Gauge Theories on Non-Spin Manifolds
J. P. Ang, Konstantinos Roumpedakis, Sahand Seifnashri
We study four-dimensional gauge theories on oriented and non-spin spacetime manifolds. On such manifolds, each line operator arises only either as a boson or a fermion. Based on ph…
Higher categorical groups and the classification of topological defects and textures
J. P. Ang, Abhishodh Prakash
Sigma models effectively describe ordered phases of systems with spontaneously broken symmetries. At low energies, field configurations fall into solitonic sectors, which are homot…
On the classification of topological defects and textures
J. P. Ang, Abhishodh Prakash
Ordered phases resulting from spontaneously broken continuous symmetries are effectively described by sigma models of maps to the coset space of Goldstone modes. A classic problem…
Generalized Kahler structures on group manifolds and T-duality
J. P. Ang, Sibylle Driezen, Martin Rocek +1
We study generalized Kahler structures on N = (2, 2) supersymmetric Wess-Zumino-Witten models; we use the well known case of SU(2) x U(1) as a toy model and develop tools that allo…
Kahler-Einstein and Kahler scalar flat supermanifolds
J. P. Ang, Martin Rocek, John Schulman
Two results regarding Kähler supermanifolds with potential are shown. First, if the supermanifold is Kähler-Einstein, then its base (the supermanifold of one lower fe…
Matrix Models for Supersymmetric Chern-Simons Theories with an ADE Classification
Daniel R. Gulotta, J. P. Ang, Christopher P. Herzog
We consider N=3 supersymmetric Chern-Simons (CS) theories that contain product U(N) gauge groups and bifundamental matter fields. Using the matrix model of Kapustin, Willett and Ya…
