Phase transitions in GLSMs and defects
Ilka Brunner, Fabian Klos, Daniel Roggenkamp
In this paper, we construct defects (domain walls) that connect different phases of two-dimensional gauged linear sigma models (GLSMs), as well as defects that embed those phases i…

Complementary Projection Defects and Decompositions
Fabian Klos, Daniel Roggenkamp
As put forward in [arXiv:1907.12339] topological quantum field theories can be projected using so-called projection defects. The projected theory and its correlation functions can…

Realizing IR theories by projections in the UV
Fabian Klos, Daniel Roggenkamp
We study bulk RG flows in the context of TQFTs and show how IR theories can be entirely represented within the respective UV theories by means of codimension-one projection defects…
