Finite-N corrections to the superconformal index of S-fold theories

On the two - loop four - derivative quantum corrections in 4 D N = 2 superconformal field theories

In N = 2, 4 superconformal field theories in four space-time dimensions, the quantum corrections with four derivatives are believed to be severely constrained by non-renormalization theorems. The strongest of these is the conjecture formulated by Dine and Seiberg in hep-th/9705057 that such terms are generated only at one loop. In this note, using the background field formulation in N = 1 super...

Index for Non-relativistic Superconformal Field Theories

We study the highest-weight representation ofN = 2 supersymmetric Schrödinger algebra which appears in non-relativistic superconformal field theories in (1+2) dimension. We define the index for the non-relativistic superconformal field theories and study its properties. As a concrete example, we compute the index for the nonrelativistic limit of N = 6 superconformal Chern-Simons-matter theory r...

The Large N Limit of Superconformal field theories and supergravity

We show that the large N limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of Anti-deSitter spacetimes, spheres and other compact manifolds. This is shown by taking some branes in the full M/string theory and then taking a low energy limit where the field theory on the brane decouples from the bulk. We ...

1 S ep 1 99 3 Bethe Ansatz for Lattice Analogues of N = 2 Superconformal Theories

The critical Boltzmann weights for lattice analogues of the N = 2 superconformal coset models G 1 ×SO(dim(G/H)) H were given in [1]. In this paper Bethe Ansatz methods are employed to calculate the spectrum of the transfer matrix obtained from these Boltzmann weights. From this the central charge and conformal weights are obtained by calculating finite-size corrections to the free energy per si...
