The superconformal index of N=1 class S fixed points
Christopher Beem, Abhijit Gadde
We investigate the superconformal index of four-dimensional N=1 superconformal field theories that arise on coincident M5 branes wrapping a holomorphic curve in a local Calabi-Yau…
On the effective hydrodynamics of FQHE
Alexander G. Abanov
We present here a classical hydrodynamic model of a two-dimensional fluid which has many properties of Fractional Quantum Hall effect. This model incorporates the FQHE relation bet…
The Seiberg-Witten Kahler Potential as a Two-Sphere Partition Function
Daniel S. Park, Jaewon Song
Recently it has been shown that the two-sphere partition function of a gauged linear sigma model of a Calabi-Yau manifold yields the exact quantum Kahler potential of the Kahler mo…
Exact two-dimensional superconformal R-symmetry and c-extremization
Francesco Benini, Nikolay Bobev
We uncover a general principle, dubbed c-extremization, which determines the exact R-symmetry of a two-dimensional unitary superconformal field theory with N=(0,2) supersymmetry. T…
Seiberg-Witten Geometry of Four-Dimensional Quiver Gauge Theories
Nikita Nekrasov, Vasily Pestun
Seiberg-Witten geometry of mass deformed superconformal ADE quiver gauge theories in four dimensions is determined. We solve the limit shape equations derived from t…
Holomorphic Blocks in Three Dimensions
Christopher Beem, Tudor Dimofte, Sara Pasquetti
We decompose sphere partition functions and indices of three-dimensional N=2 gauge theories into a sum of products involving a universal set of "holomorphic blocks". The blocks cou…
