Structures of Neural Network Effective Theories

no code implementations3 May 2023 Ian Banta, Tianji Cai, Nathaniel Craig, Zhengkang Zhang

We develop a diagrammatic approach to effective field theories (EFTs) corresponding to deep neural networks at initialization, which dramatically simplifies computations of finite-width corrections to neuron statistics.

Effective Field Theory of Dark Matter Direct Detection With Collective Excitations

2 code implementations28 Sep 2020 Tanner Trickle, Zhengkang Zhang, Kathryn M. Zurek

We develop a framework for computing light dark matter direct detection rates through single phonon and magnon excitations via general effective operators.

Detectability of Axion Dark Matter with Phonon Polaritons and Magnons

no code implementations20 May 2020 Andrea Mitridate, Tanner Trickle, Zhengkang Zhang, Kathryn M. Zurek

Collective excitations in condensed matter systems, such as phonons and magnons, have recently been proposed as novel detection channels for light dark matter.
