New symplectic singularities from gauge theories
Amihay Hanany, Guhesh Kumaran, Deshuo Liu +1
Families of gauge theories with eight supercharges are found to have a Higgs branch which is an isolated symplectic singularity. These are, in…
A Tale of Two Orbits: Non-Simply Laced Mirror
Amihay Hanany, Deshuo Liu
A three-dimensional gauge theory is constructed whose Higgs branch realizes the affine closure of the cotangent bundle of the minimal nilpotent orbit of $\mathfrak{…
Interplay of Generalised Symmetries and Moduli Spaces in 3d SCFTs
Sebastiano Garavaglia, William Harding, Deshuo Liu +1
The moduli space and generalised global symmetries of 3d superconformal field theories are investigated, with a focus on the orthosymplectic ABJ theories and thei…
3d Mirrors and Phase Diagrams of Abelian Gauge Theories
Julius F. Grimminger, Amihay Hanany, Deshuo Liu
This paper presents new developments in the study of 3d mirror symmetry and the phase structure of Abelian gauge theories. Previous works identified 3d mirrors for a specific class…
Quiver Subtraction on the Higgs Branch
Sam Bennett, Amihay Hanany, Guhesh Kumaran +3
This paper classifies all Higgs branch Higgsing patterns for simply-laced unitary quiver gauge theories with eight supercharges (including multiple loops) and introduces a Higgs br…
Actions on the quiver -- Discrete quotients on the Coulomb branch
Amihay Hanany, Guhesh Kumaran, Chunhao Li +2
This paper introduces two operations in quiver gauge theories. The first operation takes a quiver with a permutation symmetry and gives a quiver with adjoint loops. The corre…
