Towards scalable bound-to-resonance extrapolations for few- and many-body systems
Nuwan Yapa, Sebastian König, Kévin Fossez
In open quantum many-body systems, the theoretical description of resonant states of many particles strongly coupled to the continuum can be challenging. Such states are commonplac…
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…
Eigenvector continuation for emulating and extrapolating two-body resonances
Nuwan Yapa, Kévin Fossez, Sebastian König
The study of open quantum systems (OQSs), i.e., systems interacting with an environment, impacts our understanding of exotic nuclei in low-energy nuclear physics, hadrons, cold-ato…
Effective field theory analysis of the Coulomb breakup of the one-neutron halo nucleus 19C
Pierre Capel, Daniel R. Phillips, Andrew Andis +29
We analyse the Coulomb breakup of 19C measured at 67A MeV at RIKEN. We use the Coulomb-Corrected Eikonal (CCE) approximation to model the reaction and describe the one-neutron halo…
Volume extrapolation via eigenvector continuation
Nuwan Yapa, Sebastian König
We develop an extension of eigenvector continuation (EC) that makes it possible to extrapolate simulations of quantum systems in finite periodic boxes across large ranges of box si…
