Models for gapped boundaries and domain walls
We define a class of lattice models for two-dimensional topological phases with boundary such that both the bulk and the boundary excitations are gapped. The bulk part is constructed using a unitary tensor category C as in the Levin-Wen model, whereas the boundary is associated with a module category over C. We also consider domain walls (or defect lines) between different bulk phases. A domain...
متن کاملMulti-Domain Walls in Massive Supersymmetric Sigma-Models
Massive maximally-supersymmetric sigma models are shown to exhibit multiple static kink-domain wall solutions that preserve 1/2 of the supersymmetry. The kink moduli space admits a natural Kähler metric. We examine in some detail the case when the target of the sigma model is given by the co-tangent bundle of CP equipped with the Calabi metric, and we show that there exist BPS solutions corresp...
متن کاملSupersymmetric Intersecting Domain Walls in Massive Hyper-Kähler Sigma Models
The general scalar potential of D-dimensional massive sigma-models with eight supersymmetries is found for D = 3, 4. These sigma models typically admit 1/2 supersymmetric domain wall solutions and we find, for a particular hyperKähler target, exact 1/4 supersymmetric static solutions representing a nontrivial intersection of two domain walls. We also show that the intersecting domain walls can ...
متن کاملBPS Domain Walls in Models with Flat Directions
We consider BPS domain walls in the four dimensional N = 1 supersymmetric models with continuous global symmetry. Since the BPS equation is covariant under the global transformation, the solutions of the BPS walls also have the global symmetry. The moduli space of the supersymmetric vacua in such models have non-compact flat directions, and the complex BPS walls interpolating between two disjoi...
