Symmetric Space σ-model Dynamics: Internal Metric Formalism
For the symmetric space sigma model in the internal metric formalism we explicitly construct the lagrangian in terms of the axions and the dilatons of the solvable Lie algebra gauge and then we exactly derive the axion-dilaton field equations.
متن کاملSymmetric Space σ-model Dynamics: Current Formalism
After explicitly constructing the symmetric space sigma model lagrangian in terms of the coset scalars of the solvable Lie algebra gauge in the current formalism we derive the field equations of the theory.
متن کاملOn the Symmetric Space σ-model Kinematics
The solvable Lie algebra parametrization of the symmetric spaces is discussed. Based on the solvable Lie algebra gauge two equivalent formulations of the symmetric space sigma model are studied. Their correspondence is established by inspecting the normalization conditions and deriving the field transformation laws.
متن کاملDoubled Formalism, Complexification and Topological σ-Models
We study a generalization of the Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) formulation of the Aand B-models which involves a doubling of coordinates, and can be understood as a complexification of the Poisson σ-model underlying these. In the flat space limit the construction contains models obtained by twisting an N=2 supersymmetric σ-model on Hull’s doubled geometry. The curved space gen...
متن کاملThe moduli space metric for tetrahedrally symmetric 4-monopoles
The metric on the moduli space of SU(2) charge four BPS monopoles with tetrahedral symmetry is calculated using numerical methods. In the asymptotic region, in which the four monopoles are located on the vertices of a large tetrahedron, the metric is in excellent agreement with the point particle metric. We find that the four monopoles are accelerated through the cubic monopole configuration an...
