Fast emulation of quantum three-body scattering

  title={Fast emulation of quantum three-body scattering},
  author={Xilin Zhang and Richard J. Furnstahl},
We develop a class of emulators for solving quantum three-body scattering problems. They are based on combining the variational method for scattering observables and the recently proposed eigenvector continuation concept. The emulators are first trained by the exact scattering solutions of the governing Hamiltonian at a small number of points in its parameter space, and then employed to make interpolations and extrapolations in that space. Through a schematic nuclear-physics model with finite… 
Volume Extrapolation via Eigenvector Continuation
An extension of eigenvector continuation is developed that makes it possible to extrapolate simulations of quantum systems in finite periodic boxes across large ranges of box sizes by matching periodic functions at different box sizes.
Uncertainty Quantification in Breakup Reactions
Breakup reactions are one of the favored probes to study loosely bound nuclei, particularly those in the limit of stability forming a halo. In order to interpret such breakup experiments, the

Ab Initio Simulations of Light Nuclear Systems Using Eigenvector Continuation and Auxiliary Field Monte Carlo.
In this work, we discuss a new method for calculation of extremal eigenvectors and eigenvalues in systems or regions of parameter space where direct calculation is problematic. This technique relies
