B-type defects in Landau-Ginzburg models | Ilka Brunner
; Daniel Roggenkamp
; | Date: |
6 Jul 2007 | Abstract: | We consider Landau-Ginzburg models with possibly different superpotentials
glued together along one-dimensional defect lines. Defects preserving B-type
supersymmetry can be represented by matrix factorisations of the difference of
the superpotentials. The composition of these defects and their action on
B-type boundary conditions is described in this framework. The cases of
Landau-Ginzburg models with superpotential W=X^d and W=X^d+Z^2 are analysed in
detail, and the results are compared to the CFT treatment of defects in N=2
superconformal minimal models to which these Landau-Ginzburg models flow in the
IR. | Source: | arXiv, arxiv.0707.0922 | Services: | Forum | Review | PDF | Favorites |
