Higher-dimensional chaotic features and random matrix signatures following a local quench
Dmitry S. Ageev, Jacob Sonnenschein
We study the multidimensional erratic structure of correlation functions produced by local operator quenches in finite-volume free massive scalar field theory in dimensions 2 and 3…
Excited String States and D-branes from Infinite Width Neural Networks
Dmitry S. Ageev, Yulia A. Ageeva
We explore recent proposal to represent worldsheet string path integrals by integrating over parameters of a wide random-feature neural network whose output is identified with the…
Neural Network Quantum Field Theory from Transformer Architectures
Dmitry S. Ageev, Yulia A. Ageeva
We propose a neural-network construction of Euclidean scalar quantum field theories from transformer attention heads, defining -point correlators by averaging over random networ…
One-Loop Renormalization of Anisotropic Two-Scalar Quantum Field Theories
Dmitry S. Ageev, Yulia A. Ageeva
We develop a basis--covariant one--loop renormalization framework for two interacting real scalars in with the most general two--derivative Lorentz--violating quadratic for…
From Confinement to Chaos in AdS/CFT Correspondence via Non-equilibrium Local States

Dmitry S. Ageev, Yulia A. Ageeva
We study interacting scalar field theories in which different fields propagate with inequivalent spatial kinetic tensors, corresponding to different sound speeds in different direc…
Spectral form factors for curved spacetimes with horizon
Dmitry S. Ageev, Vasilii V. Pushkarev, Anastasia N. Zueva
The spectral form factor is believed to exhibit a special type of behavior called ``dip-ramp-plateau'' in chaotic quantum systems that originates from random matrix theory. This su…

Dmitry S. Ageev, Irina Ya. Aref'eva, Timofei A. Rusalev
Placing a black hole in a cavity provides a natural framework for exploring gravitational scales, thermodynamic instabilities, and effective gravity theories. In this paper, we exa…
