Quantum gravity on the bulk cone
Ahmed Almheiri, Matthew Dodelson, Zohar Komargodski
Bulk-cone singularities in holographic correlators encode propagation along bulk null geodesics. The prototypical example is an AdS black hole, where incoming null geodesics can wi…
Matrix scattering and the black hole interior
Matthew Dodelson, Henry W. Lin, Haitian Xie +1
Complex-time singularities of thermal correlators carry imprints of black hole interiors. We investigate their microscopic origin in matrix quantum mechanics at high temperature, w…
On the temperature dependence of quasinormal modes in SYK and holography
Matthew Dodelson, Om Gupta, Márk Mezei +1
It was recently found that the quasinormal modes (or Ruelle--Pollicott resonances) of the SYK model at infinite temperature form a Christmas tree shape, reminiscent of AdS black ho…
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…
Black holes from chaos
Matthew Dodelson
We study the emergence of black hole geometry from chaotic systems at finite temperature. The essential input is the universal operator growth hypothesis, which dictates the asympt…
Ringdown in the SYK model
Matthew Dodelson
We analyze thermal correlators in the Sachdev-Ye-Kitaev model away from the maximally chaotic limit. Despite the absence of a weakly curved black hole dual, the two point function…
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…
Integrability of Large-Charge Sectors in Generic 2D EFTs
Matthew Dodelson, Simeon Hellerman, Masataka Watanabe +1
It is shown that integrability is an accidental property of generic two-dimensional -symmetric asymptotically-free theories in the regime where the charge density is much lar…
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…
Gravitational orbits, double-twist mirage, and many-body scars
Matthew Dodelson, Alexander Zhiboedov
We explore the implications of stable gravitational orbits around an AdS black hole for the boundary conformal field theory. The orbits are long-lived states that eventually decay…
Chern-Simons Invariants from Ensemble Averages
Meer Ashwinkumar, Matthew Dodelson, Abhiram Kidambi +2
We discuss ensemble averages of two-dimensional conformal field theories associated with an arbitrary indefinite lattice with integral quadratic form . We provide evidence that…
Singularities of thermal correlators at strong coupling
Matthew Dodelson, Hirosi Ooguri
We analyze the singularities of the two-point function in a conformal field theory at finite temperature. In a free theory, the only singularity is along the boundary light cone. I…
The High Energy Behavior of Mellin Amplitudes
Matthew Dodelson, Hirosi Ooguri
In any consistent massive quantum field theory there are well known bounds on scattering amplitudes at high energies. In conformal field theory there is no scattering amplitude, bu…
Varying dilaton as a tracer of classical string interactions
Matthew Dodelson, Eva Silverstein, Gonzalo Torroba
We analyze tree-level string amplitudes in a linear dilaton background, motivated by its use as a gauge-invariant tracer of string interactions in scattering experiments and its ge…
Long-Range Nonlocality in Six-Point String Scattering: simulation of black hole infallers
Matthew Dodelson, Eva Silverstein
We set up a tree-level six point scattering process in which two strings are separated longitudinally such that they could only interact directly via a non-local spreading effect s…
Longitudinal nonlocality in the string S-matrix
Matthew Dodelson, Eva Silverstein
We analyze four and five-point tree-level open string S-matrix amplitudes in the Regge limit, exhibiting some basic features which indicate longitudinal nonlocality, as suggested b…
String-theoretic breakdown of effective field theory near black hole horizons
Matthew Dodelson, Eva Silverstein
We investigate the validity of the equivalence principle near horizons in string theory, analyzing the breakdown of effective field theory caused by longitudinal string spreading e…
New solutions with accelerated expansion in string theory
Matthew Dodelson, Xi Dong, Eva Silverstein +1
We present concrete solutions with accelerated expansion in string theory, requiring a small, tractable list of stress energy sources. We explain how this construction (and others…
Transition Amplitudes in de Sitter Space
Matthew Dodelson
Maldacena has shown that the wavefunction of the universe in de Sitter space can be viewed as the partition function of a conformal field theory. In this paper, we investigate this…
Effective String Theory and Nonlinear Lorentz Invariance
Ofer Aharony, Matthew Dodelson
We study the low-energy effective action governing the transverse fluctuations of a long string, such as a confining flux tube in QCD. We work in the static gauge where this action…
