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-branes from the Landau-Ginzburg phase to the geometric phase. Through their fusion with boundary conditions these defects in particular provide functors between the respective D-brane categories. The latter map (equivariant) matrix factorizations to coherent sheaves and can be formulated explicitly in terms of complexes of matrix factorizations.

  1. Defects and Phases of Higher Rank Abelian GLSMs

    hep-th 2024-12 conditional novelty 6.0 of 10

    A cutoff-truncation of the identity defect yields lift and transition defects for higher-rank abelian GLSMs, matching band restriction rules and minimal model flow defects.
