We study the dynamics near a 1+1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory, using an open string description valid at weak coupling, and a closed string description valid at strong coupling. The weak coupling description suggests that this system is invariant under eight supercharges with a particular chirality in 1+1 dimensions, and its spectrum contains chiral fermions localized at the intersection. The closed string description leads to a rather different picture -- a three dimensional Poincare invariant theory with a gap and sixteen supercharges. We show that this dramatic change in the behavior of the system is partly due to anomaly inflow. Taking it into account leads to a coherent picture, both when the fivebranes in each stack are coincident and when they are separated.

  1. (Iso)spin from Isospin in Top-Down Holography

    hep-th 2025-12 unverdicted novelty 6.0 of 10

    Supergravity backgrounds with monopoles on S2 exhibit diagonal symmetry upon uplift, causing SU(2)-SO(3) angular momentum mixing in fluctuations analogous to the Jackiw-Rebbi-Hasenfratz-'t Hooft effect.

  2. 3d $\mathcal{N}=4$ Mirror Symmetry, TQFTs, and 't Hooft Anomaly Matching

    hep-th 2024-12 conditional novelty 6.0 of 10

    Universal mass deformations of 3d N=4 Abelian gauge theories flow to Abelian spin Chern-Simons TQFTs, with mirror symmetry descending to proven level-rank dualities and 't Hooft anomalies matched via vison fractionalization.

  3. Penrose limits and TsT for fibered $I$-branes

    hep-th 2025-10 unverdicted novelty 3.0 of 10

    Analyzes TsT deformations and Penrose limits on fibered I-branes from prior work, finding preserved solvability when TsT precedes the limit and new asymptotically free or parallelizable sectors in the reverse order.
