Constructing Effective Interactions via Projection-Based Inversion
Hang Yu, Serdar Elhatisari, Sebastian König +3
We present a numerical prescription for extracting continuum scattering information from discrete spectra by constraining effective interactions inspired by effective field theory…
Radius extrapolations for two-body bound states in finite volume
Anderson Taurence, Sebastian König
Simulations of quantum systems in finite volume have proven to be a useful tool for calculating physical observables. Such studies to date have focused primarily on understanding t…
Eigenvector Continuation and Projection-Based Emulators
Thomas Duguet, Andreas Ekström, Richard J. Furnstahl +2
Eigenvector continuation is a computational method for parametric eigenvalue problems that uses subspace projection with a basis derived from eigenvector snapshots from different p…
Complex scaling in finite volume
Hang Yu, Nuwan Yapa, Sebastian König
Quantum resonances, i.e., metastable states with a finite lifetime, play an important role in nuclear physics and other domains. Describing this phenomenon theoretically is general…
Magnetic dipole operator from chiral effective field theory for many-body expansion methods
R. Seutin, O. J. Hernandez, T. Miyagi +4
Many-body approaches for atomic nuclei generally rely on a basis expansion of the nuclear states, interactions, and current operators. In this work, we derive the representation of…
Role of three-body dynamics in nucleon-deuteron correlation functions
M. Viviani, S. König, A. Kievsky +3
Correlation functions of hadrons can be accessed in high-energy collisions of atomic nuclei, revealing information about the underlying interaction. This work complements experimen…
