Supergravity in Five Dimensions
We study compactification of five dimensional ungauged N = 2 supergravity coupled to vectorand hypermultiplets on orbifold S/Z2. In the model, the vector multiplets scalar manifold is arbitrary while the hypermultiplet scalars span a generalized self dual Einstein manifold constructed by Calderbank and Pedersen. The bosonic and the fermionic sectors of the low energy effective N = 1 supergravit...
متن کاملSupergravity Breaking in Three Dimensions
We study models of spontaneous N = 2 → N = 1 supergravity breaking in three space-time dimensions and discuss the topological Higgsand super-Higgs mechanism which generates the masses for the spin-3/2 gravitino multiplet. The resulting N = 1 spectrum and its effective action is analysed.
متن کاملSupergravity in 2 + Ǫ Dimensions
Supergravity theory in 2 + ǫ dimensions is studied. It is invariant under supertransformations in 2 and 3 dimensions. One-loop divergence is explicitly computed in the background field method and a nontrivial fixed point is found. In quantizing the supergravity, a gauge fixing condition is devised which explicitly isolates conformal and superconformal modes. The renormalization of the gravitati...
متن کاملConcurrence in arbitrary dimensions
Entanglement plays central role in quantum information theory [1]. Pure state entanglement of bipartite systems is well understood in the sense that the relevant parameters for its optimal manipulation by local operations and classical communication (LOCC) have been identified and analyzed [2], [3]. Many efforts have also been devoted to the study of mixed-state entanglement. There, several pos...
