General Results for Higher Spin Wilson Lines and Entanglement in Vasiliev Theory
Ashwin Hegde, Per Kraus, Eric Perlmutter
We develop tools for the efficient evaluation of Wilson lines in 3D higher spin gravity, and use these to compute entanglement entropy in the hs Vasiliev theory that governs t…
Witten Diagrams Revisited: The AdS Geometry of Conformal Blocks
Eliot Hijano, Per Kraus, Eric Perlmutter +1
We develop a new method for decomposing Witten diagrams into conformal blocks. The steps involved are elementary, requiring no explicit integration, and operate directly in positio…
Semiclassical Virasoro Blocks from AdS Gravity
Eliot Hijano, Per Kraus, Eric Perlmutter +1
We present a unified framework for the holographic computation of Virasoro conformal blocks at large central charge. In particular, we provide bulk constructions that correctly rep…
Positivity, negativity, and entanglement
Eric Perlmutter, Mukund Rangamani, Massimiliano Rota
We explore properties of the universal terms in the entanglement entropy and logarithmic negativity in 4d CFTs, aiming to clarify the ways in which they behave like the analogous e…
Virasoro conformal blocks in closed form
Eric Perlmutter
Virasoro conformal blocks are fixed in principle by symmetry, but a closed-form expression is unknown in the general case. In this work, we provide three closed-form expansions for…
Renyi Entropies, the Analytic Bootstrap, and 3D Quantum Gravity at Higher Genus
Matthew Headrick, Alexander Maloney, Eric Perlmutter +1
We compute the contribution of the vacuum Virasoro representation to the genus-two partition function of an arbitrary CFT with central charge . This is the perturbative pure g…
