Time-reversal breaking in QCD4, walls, and dualities in 2 + 1 dimensions
Abstract 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 theory has a single gapped vacuum. However, as θ is varied through θ = π for large m there is a first order transition. For N f = 1 th...
