Expanding the Bethe/Gauge dictionary (2017)
Journal Article
Bullimore, M., Kim, H., & Lukowski, T. (2017). Expanding the Bethe/Gauge dictionary. Journal of High Energy Physics, 2017(11), Article 055. https://doi.org/10.1007/jhep11%282017%29055

We expand the Bethe/Gauge dictionary between the XXX Heisenberg spin chain and 2d N = (2, 2) supersymmetric gauge theories to include aspects of the algebraic Bethe ansatz. We construct the wave functions of off-shell Bethe states as orbifold defects... Read More about Expanding the Bethe/Gauge dictionary.

We propose a construction for the quantum-corrected Coulomb branch of a general 3d gauge theory with N=4 supersymmetry, in terms of local coordinates associated with an abelianized theory. In a fixed complex structure, the holomorphic functions on th... Read More about The Coulomb Branch of 3d N=4 Theories.

We explore aspects of the correspondence between Seifert 3-manifolds and 3d N = 2 supersymmetric theories with a distinguished abelian flavour symmetry. We give a prescription for computing the squashed three-sphere partition functions of such 3d N =... Read More about Refined 3d-3d correspondence.

Supersymmetric Casimir energy and the anomaly polynomial (2015)

We conjecture that for superconformal field theories in even dimensions, the supersymmetric Casimir energy on a space with topology S 1 × S D−1 is equal to an equivariant integral of the anomaly polynomial. The equivariant integration is defined with... Read More about Supersymmetric Casimir energy and the anomaly polynomial.

Defects and quantum Seiberg-Witten geometry (2015)

We study the Nekrasov partition function of the five dimensional U(N) gauge theory with maximal supersymmetry on ℝ4 × S 1 in the presence of codimension two defects. The codimension two defects can be described either as monodromy defects, or by coup... Read More about Defects and quantum Seiberg-Witten geometry.

We compute the supersymmetric partition function of the six-dimensional (2, 0) theory of type A N −1 on S 1 × S 5 in the presence of both codimension two and codimension four defects. We concentrate on a limit of the partition function depending on a... Read More about The superconformal index of the (2,0) theory with defects.
