Towards quantum elliptic cohomology from GLSMs
Z. Cao, E. Sharpe, H. Zhang
This paper briefly outlines a proposal for a GLSM Coulomb-branch interpretation of the quantum elliptic cohomology rings currently being developed in mathematics by Bouaziz-Huq-Kur…
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}};…
Quantum K-theory levels in physics and math
I. Huq-Kuruvilla, L. Mihalcea, E. Sharpe +1
The purpose of this paper is to describe a dictionary between Chern-Simons levels in three-dimensional gauged linear sigma models (GLSMs) and twistings of quantum K-theory in mathe…
Schubert defects in Lagrangian Grassmannians
W. Gu, L. Mihalcea, E. Sharpe +3
In this paper, we propose a construction of GLSM defects corresponding to Schubert cycles in Lagrangian Grassmannians, following recent work of Closset-Khlaif on Schubert cycles in…
Decomposition squared
Eric Sharpe, Hao Zhang
In this paper, we test and extend a proposal of Gu, Pei, and Zhang for an application of decomposition to three-dimensional theories with one-form symmetries and to quantum K theor…
Quantum cohomology from mixed Higgs-Coulomb branches
W. Gu, I. V. Melnikov, E. Sharpe
We generalize Coulomb-branch-based gauged linear sigma model (GLSM)-based computations of quantum cohomology rings of Fano spaces. Typically such computations have focused on GLSMs…
Quantum K theory rings of partial flag manifolds
W. Gu, L. Mihalcea, E. Sharpe +3
In this paper we use three-dimensional gauged linear sigma models to make physical predictions for Whitney-type presentations of equivariant quantum K theory rings of partial flag…
A proposal for nonabelian (0,2) mirrors
W. Gu, J. Guo, E. Sharpe
In this paper we give a proposal for mirrors to (0,2) supersymmetric gauged linear sigma models (GLSMs), for those (0,2) GLSMs which are deformations of (2,2) GLSMs. Specifically,…
