Description
Three advances in Neural Quantum States for nuclear physics: (i) We develop a Pfaffian–Jastrow VMC-NQS ansatz for single-$\Lambda$ hypernuclei. Calibrated via Gaussian-process assisted LO pionless EFT it reproduces s- and p-shell binding and $\Lambda$-separation energies, capturing the proton "shrinkage" in $^{7}_{\Lambda}\mathrm{Li}$ relative to $^{6}\mathrm{Li}$; (ii) Neural Interacting Dynamical Fields (Neural-IDF) are a continuation of Madeira’s dynamical-pion QMC recast as an NQS, treating pion modes as explicit variational DOFs jointly sampled with nucleons, enabling a unified N-$\pi$ description; (iii) Excited states $-$ an explicitly $SO(3)$-equivariant backflow architecture targets $J>0$ states.
