Effective Field Theories on the Jet Bundle
Nathaniel Craig, Yu-Tse Lee
We develop a generalized field space geometry for higher-derivative scalar field theories, expressing scattering amplitudes in terms of a covariant geometry on the all-order jet bu…
Structures of Neural Network Effective Theories
Ian Banta, Tianji Cai, Nathaniel Craig +1
We develop a diagrammatic approach to effective field theories (EFTs) corresponding to deep neural networks at initialization, which dramatically simplifies computations of finite-…
Effective Field Theories as Lagrange Spaces
Nathaniel Craig, Yu-Tse Lee, Xiaochuan Lu +1
We present a formulation of scalar effective field theories in terms of the geometry of Lagrange spaces. The horizontal geometry of the Lagrange space generalizes the Riemannian ge…
On-Shell Covariance of Quantum Field Theory Amplitudes
Timothy Cohen, Nathaniel Craig, Xiaochuan Lu +1
Scattering amplitudes in quantum field theory are independent of the field parameterization, which has a natural geometric interpretation as a form of `coordinate invariance.' Ampl…
Discrete Gauge Symmetries and the Weak Gravity Conjecture
Nathaniel Craig, Isabel Garcia Garcia, Seth Koren
In theories with discrete Abelian gauge groups, requiring that black holes be able to lose their charge as they evaporate leads to an upper bound on the product of a charged partic…
Rescuing Massive Photons from the Swampland
Nathaniel Craig, Isabel Garcia Garcia
Stringent Swampland conjectures aimed at effective theories containing massive abelian vectors have recently been proposed (arXiv:1808.09966), with striking phenomenological implic…
