Universality in strongly interacting bosonic clusters
L. Madeira, F. Pederiva, U. van Kolck
We develop an effective field theory (EFT) for strongly interacting bosonic clusters, using He as a paradigmatic example of universality in systems with large scattering length…
Three- and four-boson systems expanded around the unitarity limit: Application to He molecules
Feng Wu, Xincheng Lin, Ubirajara van Kolck +1
The three- and four-boson systems with a large scattering length and a short effective range in the two-body sector are studied in the framework of Short-Range Effective Field Theo…
Improved Actions for Nuclear Effective Field Theories
U. van Kolck
Effective field theories have been successful in describing nuclei up to the alpha particle but face significant challenges for larger nuclei due to leading-order instabilities. Th…
Limits on an improved action for contact effective field theory in two-body systems
L. Contessi, M. Pavon Valderrama, U. van Kolck
We consider a possible resummation of subleading effects in two-body systems with a large scattering length as described by a short-range effective field theory (EFT). In particula…
The Four-Boson First-Excited State Near Two-Body Unitarity
Feng Wu, T. Frederico, R. Higa +1
Near two-body unitarity, the three-boson system is characterized by an approximate discrete scale invariance manifest in a geometric tower of bound states (the Efimov effect). In t…
Improved action for contact effective field theory
L. Contessi, M. Schäfer, U. van Kolck
We present an improved action for renormalizable effective field theories (EFTs) of systems near the two-body unitarity limit. The ordering of EFT interactions is constrained, but…
