Topological String Correlators from Matrix Models
Robert de Mello Koch, Lwazi Nkumane
We discuss how to compute connected matrix model correlators for operators related to the gravitational descendants of the puncture operator, for the topological A model on P^1. Th…
Heavy Operators in Superconformal Chern-Simons Theory
Robert de Mello Koch, Rocky Kreyfelt, Stephanie Smith
We study the anomalous dimensions for scalar operators in ABJM theory in the SU(2) sector. The operators we consider have a classical dimension that grows as N in the large N limit…
Finite N Quiver Gauge Theory
Robert de Mello Koch, Rocky Kreyfelt, Nkululeko Nokwara
At finite N the number of restricted Schur polynomials is greater than or equal to the number of generalized restricted Schur polynomials. In this note we study this discrepancy an…
CFT4 as SO(4,2)-invariant TFT2
Robert de Mello Koch, Sanjaye Ramgoolam
We show that correlators of local operators in four dimensional free scalar field theory can be expressed in terms of amplitudes in a two dimensional topological field theory (TFT2…
Subleading corrections to the Double Coset Ansatz preserve integrability
Robert de Mello Koch, Stuart Graham, Wandile Mabanga
In this article we compute the anomalous dimensions for a class of operators, belonging to the SU(3) sector of the theory, that have a bare dimension of order N. For these operator…
