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…
