Defects and Phases of Higher Rank Abelian GLSMs
Ilka Brunner, Daniel Roggenkamp, Christian P. M. Schneider
We construct defects describing the transition between different phases of gauged linear sigma models with higher rank abelian gauge groups, as well as defects embedding these phas…
Truncated affine Rozansky--Witten models as extended defect TQFTs
Ilka Brunner, Nils Carqueville, Pantelis Fragkos +1
We apply the cobordism hypothesis with singularities to the case of affine Rozansky--Witten models, providing a construction of extended TQFTs that includes all line and surface de…
Truncated affine Rozansky--Witten models as extended TQFTs
Ilka Brunner, Nils Carqueville, Daniel Roggenkamp
We construct extended TQFTs associated to Rozansky--Witten models with target manifolds . The starting point of the construction is the 3-category whose objects ar…
Defects and phase transitions to geometric phases of abelian GLSMs
Ilka Brunner, Lukas Krumpeck, Daniel Roggenkamp
We consider gauged linear sigma models with gauge group U(1) that exhibit a geometric as well as a Landau Ginzburg phase. We construct defects that implement the transport of D-bra…
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…
