Exact results in D = 2 supersymmetric gauge theories
A bstractWe compute exactly the partition function of two dimensional $ \mathcal{N} $ = (2, 2) gauge theories on S2 and show that it admits two dual descriptions: either as an integral over the
Holographic Wilson loops
We show that all half-BPS Wilson loop operators in = 4 SYM – which are labeled by Young tableaus – have a gravitational dual description in terms of D5-branes or alternatively in terms of D3-branes
Nonrelativistic closed string theory
We construct a Galilean invariant nongravitational closed string theory whose excitations satisfy a nonrelativistic dispersion relation. This theory can be obtained by taking a consistent low energy
A Massive Study of M2-brane Proposals
We test the proposals for the worldvolume theory of M2-branes by studying its maximally supersymmetric mass-deformation. We check the simplest prediction for the mass-deformed theory on N M2-branes:
Exact Kähler potential from gauge theory and mirror symmetry
A bstractWe prove a recent conjecture that the partition function of $ \mathcal{N} $ = (2, 2) gauge theories on the two-sphere which flow to Calabi-Yau sigma models in the infrared computes the exact
Fractional branes and boundary states in orbifold theories
We study the D-brane spectrum of = 2 string orbifold theories using the boundary state formalism. The construction is carried out for orbifolds with isolated singularities, non-isolated singularities
Gauge theory loop operators and Liouville theory
We propose a correspondence between loop operators in a family of four dimensional $$ \mathcal{N} $$ = 2 gauge theories on S4 — including Wilson, ‘t Hooft and dyonic operators — and Liouville theory
Sphere partition functions and the Zamolodchikov metric
A bstractWe study the finite part of the sphere partition function of d-dimensional Conformal Field Theories (CFTs) as a function of exactly marginal couplings. In odd dimensions, this quantity is
Correlation functions of Coulomb branch operators
A bstractWe consider the correlation functions of Coulomb branch operators in four-dimensional N$$ \mathcal{N} $$ = 2 Superconformal Field Theories (SCFTs) involving exactly one antichiral operator.
