Grassmannian σ-models and Topological- Antitopological Fusion
نویسنده
چکیده
We study the topological-antitopological fusion equations for supersymmetric σ-models on Grassmannian manifolds G(k,N). We find a basis in which the metric becomes diagonal and the tt equations become tractable. The solution for the metric of G(k,N) can then be described in terms of the metric for the CPmodels. The IR expansion helps clarify the picture of the vacua and gives the soliton numbers and masses. We also show that the tt equation for G(k,N) in the large N limit is solvable, for any k.

Solvable Models in Two-dimensional N=2 Theories
N=2 supersymmetric field theories in two dimensions have been extensively studied in the last few years. Many of their properties can be determined along the whole renormalization group flow, like their coupling dependence and soliton spectra. We discuss here several models which can be solved completely, when the number of superfields is taken to be large, by studying their topological-antitop...
متن کاملSupersymmetric σ-Models on Toric Varieties: A Test Case
In this letter we study supersymmetric σ-models on toric varieties. These manifolds are generalizations of P manifolds. We examine here σ-models, viewed as gauged linear σ-models, on one of the simplest such manifold, the blow-up of P(2,1,1), and determine their properties using the techniques of topological-antitopological fusion. We find that the model contains solitons which become massless ...
متن کاملGeometry and Integrability of Topological-Antitopological Fusion
Integrability of equations of topological-antitopological fusion (being proposed by Cecotti and Vafa) describing the ground state metric on a given 2D topological field theory (TFT) model, is proved. For massive TFT models these equations are reduced to a universal form (being independent on the given TFT model) by gauge transformations. For massive perturbations of topological conformal field ...
متن کاملTopological - Antitopological Fusion and the Large N CP N Model
We discuss the large N limit of the supersymmetric CP N models as an illustration of Cecotti and Vafa's tt * formalism. In this limit the 'tt * equation' becomes the long wavelength limit of the 2D Toda lattice, an equation first studied in the context of self-dual gravity. We show how simple finite temperature and large N techniques determine the relevant solution, and verify analytically that...
متن کاملTopological Orbifold Models and Quantum Cohomology Rings
We discuss the toplogical sigma model on an orbifold target space. We describe the moduli space of classical minima for computing correlation functions involving twisted operators, and show, through a detailed computation of an orbifold of CP by the dihedral group D4, how to compute the complete ring of observables. Through this procedure, we compute all the rings from dihedral CP orbifolds; we...
