Improved many-body expansions from eigenvector continuation
Pepijn Demol, Thomas Duguet, Andreas Ekström +7
Quantum many-body theory has witnessed tremendous progress in various fields, ranging from atomic and solid-state physics to quantum chemistry and nuclear structure. Due to the inh…
Energies and radii of light nuclei around unitarity
Sebastian König
Light nuclei fall within a regime of universal physics governed by the fact that the two-nucleon scattering lengths are large compared to the typical nuclear interaction range set…
The unitarity expansion for light nuclei
Sebastian König
I is argued here that (at least light) nuclei may reside in a sweet spot: bound weakly enough to be insensitive to the details of the interaction, but dense enough to be insensitiv…
Four-Body Scale in Universal Few-Boson Systems
Betzalel Bazak, Johannes Kirscher, Sebastian König +3
The role of an intrinsic four-body scale in universal few-boson systems is the subject of active debate. We study these systems within the framework of effective field theory. For…
Causality constraints for charged particles
Sebastian König, Dean Lee, H. -W. Hammer
In quantum systems with short-range interactions, causality imposes nontrivial constraints on low-energy scattering parameters. We investigate these causality constraints for syste…
