Vacuum stability in non-supersymmetric strings
We propose a holographic correspondence between gravitational vacuum bubbles and renormalization group flows studying entanglement entropy. In order to obtain a concrete top-down realization, we study instabilities of anti-de Sitter (AdS) flux compactifications in effective field theories that arise from the non-supersymmetric USp(32) and U(32) orientifold models and the SO(16) x SO(16) heterotic string. We frame the vacua in terms of near-horizon brane stacks, then we describe vacuum bubbles generated by branes leaving the stack, computing the associated decay rate. We conclude briefly discussing possible implications.
