Renormalization Group in far-from-equilibrium states
Vladimir Rosenhaus, Michael Smolkin
We study renormalization group flows in far-from-equilibrium states. The study is made tractable by focusing on states that are spatially homogeneous, time-independent, and scale-i…
Loop diagrams in the kinetic theory of waves
Vladimir Rosenhaus, Daniel Schubring, Md Shaikot Jahan Shuvo +1
Recent work has given a systematic way for studying the kinetics of classical weakly interacting waves beyond leading order, having analogies with renormalization in quantum field…
Interaction renormalization and validity of kinetic equations for turbulent states
Vladimir Rosenhaus, Gregory Falkovich
We consider turbulence of waves that interact weakly via four-wave scattering (sea waves, plasma waves, spin waves, and many others). In the first non-vanishing order in the intera…
Random coupling model of turbulence as a classical Sachdev-Ye-Kitaev model
Xu-Yao Hu, Vladimir Rosenhaus
We point out that a classical analog of the Sachdev-Ye-Kitaev model -- a solvable model of quantum many-body chaos, was studied long ago in the turbulence literature. Motivated by…
Photon emission from an excited string
Maurizio Firrotta, Vladimir Rosenhaus
We compute the amplitude for an excited string in any precisely specified state to decay into another excited string in any precisely specified state, via emission of a tachyon or…
Chaos in a many-string scattering amplitude
Vladimir Rosenhaus
String theory provides a compact integral expression for the tree-level scattering amplitude of an arbitrary number of light strings. We focus on amplitudes involving a few tachyon…
Chaotic scattering of highly excited strings
David J. Gross, Vladimir Rosenhaus
Motivated by the desire to understand chaos in the -matrix of string theory, we study tree level scattering amplitudes involving highly excited strings. While the amplitudes for…
The background field method and critical vector models
Mikhail Goykhman, Vladimir Rosenhaus, Michael Smolkin
We use the background field method to systematically derive CFT data for the critical vector model in three dimensions, and the Gross-Neveu model in dimensions $2\leq d \leq…
Chaos in the Quantum Field Theory -matrix
Vladimir Rosenhaus
A number of studies have shown that chaos occurs in scattering: the outgoing deflection angle is seen to be an erratic function of the impact parameter. We propose to extend this t…
Integrability and Renormalization under
Vladimir Rosenhaus, Michael Smolkin
Smirnov and Zamolodchikov recently introduced a new class of two-dimensional quantum field theories, defined through a differential change of any existing theory by the determinant…
Multipoint Conformal Blocks in the Comb Channel
Vladimir Rosenhaus
Conformal blocks are the building blocks for correlation functions in conformal field theories. The four-point function is the most well-studied case. We consider conformal blocks…
-dimensional SYK, AdS Loops, and Symbols
Junyu Liu, Eric Perlmutter, Vladimir Rosenhaus +1
We study the symbol for the conformal group, and its appearance in three seemingly unrelated contexts: the SYK model, conformal representation theory, and perturbative amplitu…
An introduction to the SYK model
Vladimir Rosenhaus
These notes are a short introduction to the Sachdev-Ye-Kitaev model. We discuss: SYK and tensor models as a new class of large N quantum field theories, the near-conformal invarian…
All point correlation functions in SYK
David J. Gross, Vladimir Rosenhaus
Large melonic theories are characterized by two-point function Feynman diagrams built exclusively out of melons. This leads to conformal invariance at strong coupling, four-poi…
A line of CFTs: from generalized free fields to SYK
David J. Gross, Vladimir Rosenhaus
We point out that there is a simple variant of the SYK model, which we call cSYK, that is invariant for all values of the coupling. The modification consists of replacing…
The Bulk Dual of SYK: Cubic Couplings
David J. Gross, Vladimir Rosenhaus
The SYK model, a quantum mechanical model of Majorana fermions , with a -body, random interaction, is a novel realization of holography. It is known that the AdS$…
A Generalization of Sachdev-Ye-Kitaev
David J. Gross, Vladimir Rosenhaus
The SYK model: fermions with a -body, Gaussian-random, all-to-all interaction, is the first of a fascinating new class of solvable large models. We generalize SYK to include…
Four-point function in the IOP matrix model
Ben Michel, Joseph Polchinski, Vladimir Rosenhaus +1
The IOP model is a quantum mechanical system of a large- matrix oscillator and a fundamental oscillator, coupled through a quartic interaction. It was introduced previously as a…
The Spectrum in the Sachdev-Ye-Kitaev Model
Joseph Polchinski, Vladimir Rosenhaus
The SYK model consists of fermions in dimensions with a random, all-to-all quartic interaction. Recently, Kitaev has found that the SYK model is maximally chaotic an…
Entanglement and RG in the vector model
Chris Akers, Omer Ben-Ami, Vladimir Rosenhaus +2
We consider the large interacting vector model on a sphere in Euclidean dimensions. The Gaussian theory in the UV is taken to be either conformally or non-conforma…
Bulk-Boundary Duality, Gauge Invariance, and Quantum Error Correction
Eric Mintun, Joseph Polchinski, Vladimir Rosenhaus
Recently, Almheiri, Dong, and Harlow have argued that the localization of bulk information in a boundary dual should be understood in terms of quantum error correction. We show tha…
Entanglement Entropy for Relevant and Geometric Perturbations
Vladimir Rosenhaus, Michael Smolkin
We continue the study of entanglement entropy for a QFT through a perturbative expansion of the path integral definition of the reduced density matrix. The universal entanglement e…
Entanglement entropy, planar surfaces, and spectral functions
Vladimir Rosenhaus, Michael Smolkin
We consider the universal part of entanglement entropy across a plane in flat space for a QFT, giving a non-perturbative expression in terms of a spectral function. We study the ch…
Entanglement Entropy Flow and the Ward Identity
Vladimir Rosenhaus, Michael Smolkin
We derive differential equations for the flow of entanglement entropy as a function of the metric and the couplings of the theory. The variation of the universal part of entangleme…
