Where's Kasner? OPE Signature of Kasner Exponents
Nejc Čeplak, Samuel Valach
At large , the analytic structure of holographic thermal correlation functions contains non-trivial information about the near-singularity region of dual black holes. In particu…
Fooling the Censor: Going beyond inner horizons with the OPE
Nejc Čeplak, Hong Liu, Andrei Parnachev +1
The analytic structure of holographic correlation functions at finite temperature contains information about curvature singularities of black holes in AdS. We compute the Operator…
Size and Shape of Rotating Strings and the Correspondence to Black Holes
Nejc Čeplak, Roberto Emparan, Andrea Puhm +1
In light of the correspondence between black holes and fundamental strings with non-zero spin, we compute the sizes of rotating strings for small, moderate, and large values of the…
Black Hole Singularity from OPE
Nejc Čeplak, Hong Liu, Andrei Parnachev +1
Eternal asymptotically AdS black holes are dual to thermofield double states in the boundary CFT. It has long been known that black hole singularities have certain signatures in bo…
The correspondence between rotating black holes and fundamental strings
Nejc Čeplak, Roberto Emparan, Andrea Puhm +1
The correspondence principle between strings and black holes is a general framework for matching black holes and massive states of fundamental strings at a point where their physic…
Vector Superstrata
Nejc Čeplak
We present the construction of several microstate geometries of the supersymmetric D1-D5-P black hole in which, within six-dimensional supergravity, the momentum charge is carried…
Linearizing the BPS Equations with Vector and Tensor Multiplets
Nejc Čeplak, Shaun Hampton, Nicholas P. Warner
We analyse the BPS equations of supergravity theory in six dimensions coupled to a vector and tensor multiplet. We show how these BPS equations can be reduced…
Resolving Black-Hole Microstructure with New Momentum Carriers
Iosif Bena, Nejc Ceplak, Shaun Hampton +3
All known horizonless black-hole microstate geometries correspond to brane sources that acquire a finite size, and hence break the spherical symmetry of the black hole. We construc…
Holographic correlators with multi-particle states
Nejc Ceplak, Stefano Giusto, Marcel R. R. Hughes +1
We derive the connected tree-level part of 4-point holographic correlators in AdS (where is or ) involving two multi-trace and…
Toroidal Tidal Effects in Microstate Geometries
Nejc Ceplak, Shaun Hampton, Yixuan Li
Tidal effects in capped geometries computed in previous literature display no dynamics along internal (toroidal) directions. However, the dual CFT picture suggests otherwise. To re…
The Regge limit of AdS holographic correlators with heavy states: towards the black hole regime
Nejc Ceplak, Marcel R. R. Hughes
We examine the Regge limit of holographic 4-point correlation functions in AdS involving two heavy and two light operators. In this kinematic regime such correlators…
Pole-skipping and Rarita-Schwinger fields
Nejc Ceplak, David Vegh
In this note we analyse the equations of motion of a minimally coupled Rarita-Schwinger field near the horizon of an anti-de Sitter-Schwarzschild geometry. We find that at special…
Fermionic pole-skipping in holography
Nejc Ceplak, Kushala Ramdial, David Vegh
We examine thermal Green's functions of fermionic operators in quantum field theories with gravity duals. The calculations are performed on the gravity side using ingoing Eddington…
Supercharging Superstrata
Nejc Ceplak, Rodolfo Russo, Masaki Shigemori
We construct a new class of smooth horizonless microstate geometries of the supersymmetric D1-D5-P black hole in type IIB supergravity. We first work in the AdS deco…
