Supersymmetric 1+1d boundary field theory
I discuss recent work with Anatoly Konechny proving a gradient formula for the boundary beta function of the general supersymmetric one-dimensional quantum system with boundary that is critical in the bulk but not at the boundary. I concentrate on some unanswered questions about which Aliosha expressed curiousity. PACS numbers: 11.10.Hi, 11.10.Kk, 11.10.Wx, 11.25.Uv, 64.60.fd One-dimensional qu...
متن کاملSupersymmetric, Integrable Boundary Field Theories
Quantum integrable models that possess N = 2 supersymmetry are investigated on the half-space. Conformal perturbation theory is used to identify some N = 2 supersymmetric boundary integrable models, and the effective boundary Landau-Ginzburg actions are constructed. It is found that N = 2 supersymmetry largely determines the boundary action in terms of the bulk, and in particular, the boundary ...
متن کاملSupersymmetric Rings in Field Theory
We study the dynamics of BPS string-like objects obtained by lifting monopole and dyon solutions of N = 2 Super-Yang-Mills theory to five dimensions. We present exact traveling wave solutions which preserve half of the supersymmetries. Upon compactification this leads to macroscopic BPS rings in four dimensions in field theory. Due to the fact that the strings effectively move in six dimensions...
متن کاملBoundary Conformal Field Theory∗
Boundary conformal field theory (BCFT) is simply the study of conformal field theory (CFT) in domains with a boundary. It gains its significance because, in some ways, it is mathematically simpler: the algebraic and geometric structures of CFT appear in a more straightforward manner; and because it has important applications: in string theory in the physics of open strings and D-branes, and in ...
متن کاملSupersymmetric Quantum Field Theory: Indefinite Metric
We study the recently introduced Krein structure (indefinite metric) of the N = 1 supersymmetry and present the way into physical applications outside path integral methods. From the mathematical point of view some perspectives are mentioned at the end of the paper.
