Nuclear lattice effective field theory as a testing ground for -cluster structures in
Gianluca Stellin, Serdar Elhatisari, Timo A. Lähde +1
The framework of nuclear lattice effective field theory (NLEFT) is applied to , with the perspective of obtaining a model-independent density map of the geometry…
Spectrum and electromagnetic properties of in the Geometric -cluster Model with symmetry at leading order
Gianluca Stellin, Karl-Heinz Speidel
The relevance of the point-symmetry group for the prediction of spectrum and electromagnetic properties of the nucleus is discussed in the fra…
Electromagnetic Selection Rules for in a Cluster Model with Symmetry
Gianluca Stellin, Karl-Heinz Speidel
In the framework of a macroscopic -cluster model, the structural properties and the spectroscopy of the nucleus are investigated. Special attention is devoted…
Wavefunction matching for solving quantum many-body problems
Serdar Elhatisari, Lukas Bovermann, Yuanzhuo Ma +15
Ab initio calculations play an essential role in our fundamental understanding of quantum many-body systems across many subfields, from strongly correlated fermions to quantum chem…
Magnetic dipole moments as a strong signature for -clustering in even-even self-conjugate nuclei
Gianluca Stellin, Karl-Heinz Speidel, Ulf-G. Meißner
We investigate the magnetic dipole moments in even-even self-conjugate nuclei from to . For the latter, the measured gyromagnetic factors of…
Two-Fermion Bound and Scattering States in a Finite Volume including QED in P-Wave and Beyond
Gianluca Stellin
Introducing a short range force coupling the spinless fermions to one unit of angular momentum in the framework of pionless EFT, we first report the two-body scattering amplitudes…
P-Wave Two-Particle Bound and Scattering States in a Finite Volume including QED
Gianluca Stellin, Ulf-G. Meißner
The mass shifts for two-fermion bound and scattering P-wave states subject to the long-range interactions due to QED in the non-relativistic regime are derived. Introducing a short…
Breaking and restoration of rotational symmetry in the low-energy spectrum of light alpha-conjugate nuclei on the lattice I: and
G. Stellin, S. Elhatisari, U. -G. Meißner
The breaking of rotational symmetry on the lattice for bound eigenstates of the two lightest alpha conjugate nuclei is explored. Moreover, a macroscopic alpha-cluster model is used…
Electromagnetic selection rules in the triangular alpha-cluster model of 12C
G. Stellin, L. Fortunato, A. Vitturi
After recapitulating the procedure to find the bands and the states occurring in the alpha-cluster model of C in which the clusters are placed at the vert…
