We consider classical, pure Yang-Mills theory in a box. We show how a set of static electric fields that solve the theory in an adiabatic limit correspond to geodesic motion on the space of vacua, equipped with a particular Riemannian metric that we identify. The vacua are generated by spontaneously broken global gauge symmetries, leading to an infinite number of conserved momenta ...

We revisit the holographic dictionary for a free massless scalar in AdS3, focusing on the ‘singleton’ solutions for which the boundary profile is an arbitrary chiral function. We look for consistent boundary conditions which include this class of solutions. On one hand, we give a no-go argument that they cannot be interpreted within any boundary condition which preserves full ...

We provide a semiclassical description of framed BPS states in four-dimensional \( \mathcal{N}=2 \) super Yang-Mills theories probed by ’t Hooft defects, in terms of a supersymmetric quantum mechanics on the moduli space of singular monopoles. Framed BPS states, like their ordinary counterparts in the theory without defects, are associated with the L 2 kernel of certain Dirac ...

We present a new family of asymptotic AdS 3 × S 2 solutions to eleven dimensional supergravity compactified on a Calabi-Yau threefold. They originate from the backreaction of S 2-wrapped M2-branes, which play a central role in the deconstruction proposal for the microscopic interpretation of the D4-D0 black hole entropy. We show that they are free of possible pathologies such as ...

We revisit supersymmetric solutions to five dimensional ungauged N=1 supergravity with dynamic hypermultiplets. In particular we focus on a truncation to the axion-dilaton contained in the universal hypermultiplet. The relevant solutions are fibrations over a four-dimensional Kähler base with a holomorphic axion-dilaton. We focus on solutions with additional symmetries and classify ...

We study intersecting brane systems that realize a class of singular monopole configurations in four-dimensional Yang-Mills-Higgs theory. Singular monopoles are solutions to the Bogomolny equation on \( {\mathrm{\mathbb{R}}}^3 \) with a prescribed number of singularities corresponding to the insertion of ’t Hooft defects. We use the brane construction to motivate a recent ...

We compute the dimension of the moduli space of gauge-inequivalent solutions to the Bogomolny equation on ℝ3 with prescribed singularities corresponding to the insertion of a finite number of ’t Hooft defects. We do this by generalizing the methods of C. Callias and E. Weinberg to the case of ℝ3 with a finite set of points removed. For a special class of Cartan-valued backgrounds ...

Depending on the value of the coupling, BPS states of type II string theory compactified on a Calabi-Yau manifold can be described as multicenter supergravity solutions or as BPS states in a quiver gauge theory. While states that spread into the Coulomb-branch states can be mapped one-to-one to supergravity states, this is not automatically so for the majority of Higgs-branch ...

We construct a family of supersymmetric solutions to supergravity in three dimensions with a negative cosmological constant, that correspond to type IIB seven branes wrapped on an internal S3×T4. These solutions are generalizations of the three dimensional Gödel universe and have closed timelike curves. We propose an enhançon-like mechanism for excising the closed timelike curve ...

We determine, in two independent ways, the number of BPS quantum states arising from supergravity degrees of freedom in a system with fixed total D4D0 charge. First, we count states generated by quantizing the spacetime degrees of freedom of “entropyless” multicentered solutions consisting of \( \overline {\text{D0}} \)-branes bound to a D6\( \overline {\text{D6}} \) pair. Second, ...
