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…

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…

Disparity in sound speeds: implications for elastic unitarity and the effective potential in quantum field theory theory
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…
