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…

Unwinding Short-Range Entanglement
Abhishodh Prakash, Juven Wang, Tzu-Chieh Wei
Symmetry-Protected Topological (SPT) phases are gapped phases of quantum matter protected by global symmetries that cannot be adiabatically deformed to a trivial phase without brea…
