A double-scaling semiclassical limit in the Abelian Higgs model computes the cusp anomalous dimension to NNLO in the gauge coupling while resumming scalar self-interactions to all orders, bridging perturbative and large-charge regimes.
Dynamical EoW branes in rotating BTZ black holes are mapped to JT gravity, yielding BCFT thermodynamics and indicating possible interior transitions between single and double-joint configurations.
