Emulating Recombination with Neural Networks using Universal Differential Equations

Ben Pennell, Zack Li, James M. Sullivan · 2024

With an aim towards modeling cosmologies beyond the $\Lambda$CDM paradigm, we demonstrate the automatic construction of recombination history emulators while enforcing a prior of causal dynamics. Thes…

Constraint of pionless EFT using two-nucleon spectra from lattice QCD

William Detmold, Fernando Romero-Lopez, Phiala E. Shanahan · 2023

Finite-volume pionless effective field theory (FVEFT$_{ \pi\!/ }$) at next-to-leading order (NLO) is used to analyze the two-nucleon lattice QCD spectrum of Ref.~\cite{Amarasinghe:2021lqa}, performed …
