A-Model Correlators from the Coulomb Branch

چکیده
We compute the contribution of discrete Coulomb vacua to A-Model correlators in toric Gauged Linear Sigma Models. For models corresponding to a compact variety, this determines the correlators at arbitrary genus. For non-compact examples, our results imply the surprising conclusion that the quantum cohomology relations break down for a subset of the correlators.

The Coulomb Branch in Gauged Linear Sigma Models
We investigate toric GLSMs as models for tachyon condensation in type II strings on space-time non-supersymmetric orbifold singularities. The A-model correlators in these theories satisfy a set of relations related to the topology of the resolved orbifold. Using these relations we compute the correlators and find a non-trivial chiral ring in the IR, which we interpret as supported on isolated C...
متن کاملCurrent correlators in the Coulomb branch of N = 4 SYM
We study correlators of R-symmetry currents in the Coulomb branch of N = 4 supersymmetric gauge theory in the large-N limit, using the AdS/CFT correspondence. In particular, we consider gauge fields in the presence of gravity and scalar fields parameterizing the coset SL(6, IR)/SO(6) in the context of five-dimensional gauged supergravity. From a ten-dimensional point of view these backgrounds c...
متن کاملDevelopment of a New Dynamic Friction Model for Analytical Modeling of Elliptical Vibration Assisted Turning Process
A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...

متن کامل0 v 2 1 D ec 1 99 9 Correlation functions in the Coulomb branch of N = 4 SYM from AdS / CFT correspondence
In the present paper we study S(N) → S(U (N/2) × U (N/2)) symmetry breaking in N = 4 SY M via AdS/CFT correspondence. We consider two stacks of N/2 parallel D3 branes separated by a distance 2 d. In this case there is mixing between the different l-wave dilatonic KK modes. We calculate certain the two point correlation functions in the dual gauge theory. Due to mode mixing, the diagonal correla...
