abstract
We use the monodromy method to compute expectation values of an arbitrary number of light operators in finitely excited ("heavy") eigenstates of holographic 2D CFT. For eigenstates with scaling dimensions above the BTZ threshold, these behave thermally up to small corrections, with an effective temperature determined by the heavy state. Below the threshold we find oscillatory and not decaying behavior. As an application of these results we compute the expectation of the out-of-time order arrangement of four light operators in a heavy eigenstate, i.e. a six-point function. Above the threshold we find maximally scrambling behavior with Lyapunov exponent $2\pi T_{\rm eff}$. Below threshold we find that the eigenstate OTOC shows persistent harmonic oscillations.

Signatures of Bulk Black Hole Merger from Semi-classical 2d CFT
A semi-classical CFT calculation with the monodromy method finds a transition to an intermediate black hole phase for heavy scattering states before the external operators reach the BTZ mass threshold.

Projections and teleportation of operator quenches in CFT
In a 2D CFT, projecting an operator quench onto a Cardy state produces Renyi entropies with a surprising even/odd n dependence, indicating imperfect teleportation and obstructing the n to 1 von Neumann limit.
