摘要

Using the D1D5 CFT we investigate transitions involving a member of a certain class of states called superstrata states, which are holographically dual to certain smooth, horizonless, 1/8-BPS, three-charge black hole microstates known as superstrata. We study these transitions by deforming the CFT away from the free orbifold point using a marginal deformation which contains a twist operator and a supercharge operator. We apply two marginal deformations to an initial state containing a graviton acting on a superstratum state. We compute amplitudes capturing transitions from this state to a graviton acting on a microstratum state, a member of a class of states which are holographically dual to certain smooth, horizonless, non-BPS, three-charge black hole microstates known as microstrata, non-BPS analogues of superstrata. We compare the resulting amplitude for various initial and final state energies to determine the preferred transition process. This may give hints as to how the dual superstratum geometry may preferentially back-react in this setting.
