Large Charge Jets in SYM Energy Correlators
Alba Grassi, Cristoforo Iossa, Luigi Tizzano +1
We compute the energy-energy correlator in a state created by a heavy canonical operator of scaling dimension in SYM, at fixed and arbitrary value…
OPE = QNM
Paolo Arnaudo, Cristoforo Iossa, Robin Karlsson +1
At microscopic scales the linear response of thermal states of large- CFTs is governed by a thermal operator product expansion (OPE), while at large scales response is governed…
Bouncing off a stringy singularity
Matthew Dodelson, Cristoforo Iossa, Robin Karlsson
A sharp signature of the black hole singularity in holography is a divergence in the boundary thermal two-point function at a specific point in the complex time plane. This diverge…
5-Dimensional Gravitational Raman Scattering: Scalar Wave Perturbations in Schwarzschild-Tangherlini Spacetime
Samim Akhtar, Yilber Fabian Bautista, Cristoforo Iossa +1
In this Letter, we study scalar wave perturbations of arbitrary frequency to the 5D Schwarzschild-Tangherlini black hole (STBH) within general relativity. For the first time, we de…
Large charge meets semiclassics in super Yang-Mills
Augustus Brown, Francesco Galvagno, Alba Grassi +2
We study the large-charge sector of super Yang-Mills theory (SYM) with gauge group by constructing a special class of half-BPS heavy operators, termed "cano…
Matrix models for extremal and integrated correlators of higher rank
Alba Grassi, Cristoforo Iossa
We study extremal and integrated correlators of half-BPS operators in four-dimensional SQCD and SYM with gauge group. We focus on the large…
Black Hole Perturbation Theory Meets CFT: Kerr Compton Amplitudes from Nekrasov-Shatashvili Functions
Yilber Fabian Bautista, Giulio Bonelli, Cristoforo Iossa +2
We present a novel study of Kerr Compton amplitudes in a partial wave basis in terms of the Nekrasov-Shatashvili (NS) function of the confluent Heun equation (CHE). Remarkably, NS-…
Black hole bulk-cone singularities
Matthew Dodelson, Cristoforo Iossa, Robin Karlsson +2
Lorentzian correlators of local operators exhibit surprising singularities in theories with gravity duals. These are associated with null geodesics in an emergent bulk geometry. We…
The black hole behind the cut
Stefano Giusto, Cristoforo Iossa, Rodolfo Russo
We study the analytic structure of the heavy-heavy-light-light holographic correlators in the supergravity approximation of the AdS/CFT duality. As an explicit e…
A thermal product formula
Matthew Dodelson, Cristoforo Iossa, Robin Karlsson +1
We show that holographic thermal two-sided two-point correlators take the form of a product over quasi-normal modes (QNMs). Due to this fact, the two-point function admits a natura…
Holographic thermal correlators from supersymmetric instantons
Matthew Dodelson, Alba Grassi, Cristoforo Iossa +2
We present an exact formula for the thermal scalar two-point function in four-dimensional holographic conformal field theories. The problem of finding it reduces to the analysis of…
Irregular Liouville correlators and connection formulae for Heun functions
Giulio Bonelli, Cristoforo Iossa, Daniel Panea Lichtig +1
We perform a detailed study of a class of irregular correlators in Liouville Conformal Field Theory, of the related Virasoro conformal blocks with irregular singularities and of th…
Conformality Loss, Walking, and 4D Complex Conformal Field Theories at Weak Coupling
Francesco Benini, Cristoforo Iossa, Marco Serone
Four-dimensional gauge theories with matter can have regions in parameter space, often dubbed conformal windows, where they flow in the infrared to non-trivial conformal field theo…
