Abstract Three-dimensional Yang-Mills-Chern-Simons theory has the peculiar property that its one-form symmetry defects have nontrivial braiding, namely they are charged under the same symmetry they generate, which is then anomalous. This poses a few

Abstract Symmetries corresponding to local transformations of the fundamental fields that leave the action invariant give rise to (invertible) topological defects, which obey group-like fusion rules. One can construct more general (codimension-one) t

Abstract We study the vacuum structure of three-dimensional SU(N ) gauge theory coupled to a Chern-Simons term at level k and to F fundamental Dirac fermions. We use a large N holographic description based on a D3/D7 system in type IIB string theory

Abstract We study the phase diagram of SU (N) gauge theory in three space-time dimensions with a Chern-Simons term at level k, coupled to two sets of fundamental fermions with masses m 1 and m 2, respectively. The two-dimensional phase diagram that w

Abstract Massive QCD at θ = π breaks CP spontaneously and admits domain walls whose dynamics and phases depend on the number of flavors and their masses. We discuss these issues within the Witten-Sakai-Sugimoto model of holographic QCD. Besides sho

We consider a 4d scalar field coupled to large N free or critical O(N) vector models, either bosonic or fermionic, on a 3d boundary. We compute the β function of the classically marginal bulk/boundary interaction at the first non-trivial order in th

Using gauge/gravity duality as a tool, we compute the strong sector, isospin-breaking induced contribution to the neutron-proton mass difference in the Witten-Sakai-Sugimoto model of large N QCD with two nondegenerate light flavors. The mass differen

We construct unitary, stable, and interacting conformal boundary conditions for a free massless scalar in four dimensions by coupling it to edge modes living on a boundary. The boundary theories we consider are bosonic and fermionic QED$_3$ with $N_f
