The field of model order reduction (MOR) is growing in importance due to its ability to extract the key insights from complex simulations while discarding computationally burdensome and superfluous information. We provide an overview of MOR methods for the creation of fast & accurate emulators of memory- and compute-intensive nuclear systems. As an example, we describe how "eigenvector continuation" is a special case of a much more general and well-studied MOR formalism for parameterized systems. We continue with an introduction to the Ritz and Galerkin projection methods that underpin many such emulators, while pointing to the relevant MOR theory and its successful applications along the way. We believe that this will open the door to broader applications in nuclear physics and facilitate communication with practitioners in other fields.

A Gaussian Process framework for constraining the nuclear equation of state from microscopic calculations with correlated uncertainties
GPDiff fits a hierarchical Gaussian process to microscopic asymmetric-matter energies and propagates correlated uncertainties to EOS parameters and neutron-star matter properties.

PMM-IMSRG emulator for the nuclear equation of state with quantified uncertainties
A parametric-matrix-model emulator reproduces IMSRG nuclear-matter energies with calibrated conformal-prediction error bars, enabling Bayesian fitting of three-nucleon couplings to saturation properties.

Constraining Hamiltonians from chiral effective field theory with neutron-star data
Neutron-star data, run through fast emulators, directly constrain the six two-nucleon low-energy constants of an N2LO chiral Hamiltonian, with future detectors able to strongly pin down the 3P1 channel.
