Stability of baryonic black membranes
Abstract
Near-extremal black membranes with topological (baryonic) U ( 1 ) B charge of M theory compactified on the coset space M 1 , 1 , 0 are stable. M 1 , 1 , 0 coset is a Z 2 -invariant truncation of a larger Q 1 , 1 , 1 coset, with diagonal U ( 1 ) B ≡ U ( 1 ) B , + ⊂ U ( 1 ) B 2 symmetry of the latter. We show that the baryonic black membranes of M-theory M 1 , 1 , 0 compactifications are unstable to Z 2 -odd gravitational bulk gauge and scalar fluctuations, but only if this bulk scalar is identified with the holographically dual 2 + 1 -dimensional superconformal gauge theory operator of conformal dimension Δ = 1 . The instability is associated with the unstable charge transport of the off-diagonal U ( 1 ) B , − ⊂ U ( 1 ) B 2 symmetry.
