Identifiability Limits of Gravitational Wave Phase Deviations: Multiclass Classification with a Multihead Neural Network
Lavinia Heisenberg, Shayan Hemmatyar
We study how well gravitational-wave phase deviations can be identified using a neural network with classification and regression heads. The classification head distinguishes gener…
Testing General Relativity Through Gravitational Wave Classification: A Convolutional Neural Network Framework
Lavinia Heisenberg, Shayan Hemmatyar, Hector Villarrubia-Rojo
We present a machine learning framework for testing general relativity (GR) with gravitational wave signals from binary black hole mergers. Using the source parameters of 173 BBH e…
A Non-Renormalization Theorem for Local Functionals in Ghost-Free Vector Field Theories Coupled to Dynamical Geometry
Lavinia Heisenberg, Shayan Hemmatyar, Nadine Nussbaumer
We establish a non-renormalization theorem for a class of ghost-free local functionals describing massive vector field theories coupled to dynamical geometry. Under the assumptions…
Kinetic Field Theory: Higher-Order Perturbation Theory
Lavinia Heisenberg, Shayan Hemmatyar, Stefan Zentarra
We give a detailed exposition of the formalism of Kinetic Field Theory (KFT) with emphasis on the perturbative determination of observables. KFT is a statistical non-equilibrium cl…
