Phases Of Adjoint QCD And Dualities
Jaume Gomis, Zohar Komargodski, Nathan Seiberg
We study 2+1 dimensional gauge theories with a Chern-Simons term and a fermion in the adjoint representation. We apply general considerations of symmetries, anomalies, and renormal…
Time-Reversal Breaking in QCD, Walls, and Dualities in 2+1 Dimensions
Davide Gaiotto, Zohar Komargodski, Nathan Seiberg
We study Quantum Chromodynamics (QCD) in 3+1 dimensions with degenerate fundamental quarks with mass and a -parameter. For generic and the theory has a…
The Sum Over Topological Sectors and in the 2+1-Dimensional -Model
Daniel S. Freed, Zohar Komargodski, Nathan Seiberg
We discuss the three spacetime dimensional model and specialize to the model. Because of the Hopf map $π_3(\mathbb{C}\mathbb{P}^1)…
A Symmetry Breaking Scenario for QCD
Zohar Komargodski, Nathan Seiberg
We consider the dynamics of 2+1 dimensional gauge theory with Chern-Simons level and fundamental fermions. By requiring consistency with previously suggested dual…
Walls, Anomalies, and (De)Confinement in Quantum Anti-Ferromagnets
Zohar Komargodski, Tin Sulejmanpasic, Mithat Ünsal
We consider the Abelian-Higgs model in 2+1 dimensions with instanton-monopole defects. This model is closely related to the phases of quantum anti-ferromagnets. In the presence of…
Comments on Abelian Higgs Models and Persistent Order
Zohar Komargodski, Adar Sharon, Ryan Thorngren +1
A natural question about Quantum Field Theory is whether there is a deformation to a trivial gapped phase. If the underlying theory has an anomaly, then symmetric deformations can…
