Bayesian parameter estimation in EFT using Hamiltonian Monte Carlo

Isak Svensson, Andreas Ekström, Christian Forssén

The number of low-energy constants (LECs) in chiral effective field theory (EFT) grows rapidly with increasing chiral order, necessitating the use of Markov chain Monte Carlo te…

Wave-packet continuum discretisation for nucleon-nucleon scattering predictions

Sean B. S. Miller, Andreas Ekström, Christian Forssén

In this paper we analyse the efficiency, precision, and accuracy of computing elastic nucleon-nucleon (NN) scattering amplitudes with the wave-packet continuum discretisation metho…

Rigorous constraints on three-nucleon forces in chiral effective field theory from fast and accurate calculations of few-body observables

S. Wesolowski, I. Svensson, A. Ekström +4

We explore the constraints on the three-nucleon force (3NF) of chiral effective field theory (EFT) that are provided by bound-state observables in the and sectors. O…

Bayesian optimization in ab initio nuclear physics

A. Ekström, C. Forssén, C. Dimitrakakis +5

Theoretical models of the strong nuclear interaction contain unknown coupling constants (parameters) that must be determined using a pool of calibration data. In cases where the mo…

Three-body halo states in effective field theory

Emil Ryberg, Christian Forssén, Lucas Platter

In this paper we study the renormalization of Halo effective field theory applied to the Helium-6 halo nucleus seen as an alpha-neutron-neutron three-body state. We include the 0+…

Strongly interacting few-fermion systems in a trap

C. Forssén, R. Lundmark, J. Rotureau +2

Few- and many-fermion systems on the verge of stability, and consisting of strongly interacting particles, appear in many areas of physics. The theoretical modeling of such systems…
