Symmetries and strings of adjoint QCD2

Z Komargodski, K Ohmori, K Roumpedakis… - Journal of High Energy …, 2021 - Springer
A bstract We revisit the symmetries of massless two-dimensional adjoint QCD with gauge
group SU (N). The dynamics is not sufficiently constrained by the ordinary symmetries and …

Non-invertible self-duality defects of Cardy-Rabinovici model and mixed gravitational anomaly

Y Hayashi, Y Tanizaki - Journal of High Energy Physics, 2022 - Springer
A bstract We study properties of self-duality symmetry in the Cardy-Rabinovici model. The
Cardy-Rabinovici model is the 4d U (1) gauge theory with electric and magnetic matters, and …

Flag manifold sigma models: spin chains and integrable theories

I Affleck, D Bykov, K Wamer - Physics Reports, 2022 - Elsevier
This review is dedicated to two-dimensional sigma models with flag manifold target spaces,
which are generalizations of the familiar CP n− 1 and Grassmannian models. They naturally …

Time-reversal breaking in QCD4, walls, and dualities in 2+ 1 dimensions

D Gaiotto, Z Komargodski, N Seiberg - Journal of High Energy Physics, 2018 - Springer
A bstract We study SU (N) Quantum Chromodynamics (QCD) in 3+ 1 dimensions with N f
degenerate fundamental quarks with mass m and a θ-parameter. For generic m and θ the …

Semi-Abelian gauge theories, non-invertible symmetries, and string tensions beyond N-ality

M Nguyen, Y Tanizaki, M Ünsal - Journal of High Energy Physics, 2021 - Springer
A bstract We study a 3d lattice gauge theory with gauge group U (1) N− 1⋊ SN, which is
obtained by gauging the SN global symmetry of a pure U (1) N− 1 gauge theory, and we call …

Modified instanton sum in QCD and higher-groups

Y Tanizaki, M Ünsal - Journal of High Energy Physics, 2020 - Springer
A bstract We consider the SU (N) Yang-Mills theory, whose topological sectors are restricted
to the instanton number with integer multiples of p. We can formulate such a quantum field …

Anomaly constraints on deconfinement and chiral phase transition

H Shimizu, K Yonekura - Physical Review D, 2018 - APS
We study the constraints on thermal phase transitions of SU (N c) gauge theories by using
the't Hooft anomaly involving the center symmetry and chiral symmetry. We consider two …

New heavenly double copies

E Chacón, H García-Compeán, A Luna… - Journal of High Energy …, 2021 - Springer
A bstract The double copy relates scattering amplitudes and classical solutions in Yang-Mills
theory, gravity, and related field theories. Previous work has shown that this has an explicit …

Walls, anomalies, and deconfinement in quantum antiferromagnets

Z Komargodski, T Sulejmanpasic, M Ünsal - Physical Review B, 2018 - APS
We consider the Abelian-Higgs model in 2+ 1 dimensions with instanton-monopole defects.
This model is closely related to the phases of quantum antiferromagnets. In the presence of …

Circle compactification and't Hooft anomaly

Y Tanizaki, T Misumi, N Sakai - Journal of High Energy Physics, 2017 - Springer
A bstract Anomaly matching constrains low-energy physics of strongly-coupled field
theories, but it is not useful at finite temperature due to contamination from high-energy …
