Effervescent spikes in M-theory

Year: 2026

Type: article

Abstract: A bstract AdS 3 × S 3 × S 3 solutions warped over a Riemann surface, Σ, are indexed by a parameter, γ , that defines the superconformal algebra, D (2, 1; γ ) ⨁ D (2, 1; γ ) they preserve. We show that these solutions come from multiple back-reacted M2-M5 spikes, and that different values of γ correspond to different scaling limits of the same M2-M5 solutions. We find that when γ switches from positive to negative, the infrared region of the AdS 3 switches from the tip of spikes, far from the M5 branes, to the bottom of the spikes, far from the M2 branes. We also explain how the bubbling negative- γ solutions emerge from the geometric transition of multiple M2-M5 spikes.
