Refined Vafa-Witten invariants for toric surfaces from supersymmetric localization in 5D gauge theory
Osama Khlaif, Boris Pioline, Alessandro Tanzini
We study the partition function of five-dimensional supersymmetric Yang-Mills (SYM) theory with an adjoint hypermultiplet of mass on a toric Kä…
On the Schubert calculus of the quantum K-theory for partial flag manifolds: a 3d A-model perspective
Zhihao Duan, Osama Khlaif, Hao Zou
We further investigate the 3d gauged linear sigma model (GLSM)/~quantum K-theory correspondence for partial flag manifolds . This is a 3d uplif…
Schubert line defects in 3d GLSMs, part I: Complete flag manifolds and quantum Grothendieck polynomials
Cyril Closset, Wei Gu, Osama Khlaif +3
We construct new half-BPS line defects in 3d supersymmetric quiver gauge theories whose Higgs branches are complete flag manifolds . Upon circle co…
Schubert line defects in 3d GLSMs, part II: Partial flag manifolds and parabolic quantum polynomials
Cyril Closset, Wei Gu, Osama Khlaif +3
We construct Schubert line defects in the 3d supersymmetric gauged linear sigma model (GLSM) with target space a partial flag manifold $X={\rm Fl}({\boldsymbol{k}};…
Aspects of 4d gauge theories from M-theory: decomposition, automorphisms, and generalised symmetries
Osama Khlaif, Marwan Najjar
We study the decomposition of 4d gauge theories with Lie algebras of type , , and , realized via M-theory geo…
The 3d -model and generalised symmetries, Part I: bosonic Chern-Simons theories
Cyril Closset, Elias Furrer, Adam Keyes +1
The 3d -model is a two-dimensional approach to the computation of supersymmetric observables of three-dimensional supersymmetric gauge theories. In principle, it…
One-form symmetries and the 3d -model: Topologically twisted indices and CS theories
Cyril Closset, Elias Furrer, Osama Khlaif
We study three-dimensional supersymmetric Chern-Simons-matter gauge theories with a one-form symmetry in the -model formalism on . We explicitly c…
New results on 3d SQCD and its 3d GLSM interpretation
Cyril Closset, Osama Khlaif
In this note, we review some new results we recently obtained about the infrared physics of 3d SQCD with a unitary gauge group, in particular in the presence of a n…
Grothendieck lines in 3d SQCD and the quantum K-theory of the Grassmannian
Cyril Closset, Osama Khlaif
We revisit the 3d GLSM computation of the equivariant quantum K-theory ring of the complex Grassmannian from the perspective of line defects. The 3d GLSM onto $X={\rm Gr}(N_c, n_f)…
On the Witten index of 3d unitary SQCD with general CS levels
Cyril Closset, Osama Khlaif
We consider unitary SQCD, a three-dimensional supersymmetric Chern-Simons-matter theory consisting of one vector multiplet coupled to fu…
Twisted indices, Bethe ideals and 3d infrared dualities
Cyril Closset, Osama Khlaif
We study the topologically twisted index of 3d supersymmetric gauge theories with unitary gauge groups. We implement a Gröbner basis algorithm for computing the $Σ_…
Virasoro Constraint for Uglov Matrix Model
Osama Khlaif, Taro Kimura
We study the root of unity limit of -deformed Virasoro matrix models, for which we call the resulting model Uglov matrix model. We derive the associated V…
