A practical approach to perturbative corrections to few-body observables
Sourav Mondal, Martin Schäfer, Mirko Bagnarol +3
We formulate two methods to facilitate the calculation of perturbative corrections to quantum few-body observables. Both techniques are designed for a numerical realization in comb…
Spectrum of light nuclei in a finite volume
Roee Yaron, Betzalel Bazak, Martin Schäfer +1
Lattice quantum chromodynamics calculations of multi-baryon systems with physical quark masses would start a new age of ab initio predictions in nuclear physics. Performed on a fin…
In-medium isospin impurity from charge symmetry breaking in the mirror hypernuclei
M. Schäfer, N. Barnea, A. Gal
The separation energies in the mirror hypernuclei exhibit large charge symmetry breaking (CSB). Analyzing this CSB within pionless effective fiel…
matter and its stability
J. Hrtánková, M. Schäfer, J. Mareš +3
We performed calculations of nuclear systems composed solely of hyperons, aiming at exploring the possibility of existence of absolutely stable matter. We considered $Λ…
Multi-fermion systems with contact theories
Martin Schäfer, Lorenzo Contessi, Johannes Kirscher +1
We address the question of minimal requirements for the existence of quantum bound states. In particular, we demonstrate that a few-body system with zero-range momentum-independent…
On the Stability of Matter
J. Hrtánková, N. Barnea, E. Friedman +3
A hypothesis of absolutely stable strange hadronic matter composed of baryons, here denoted , is tested within many-body calculations performed using the Relativisti…
-matter: stable or unstable?
Jaroslava Hrtánková, Nir Barnea, Eliahu Friedman +3
A recent suggestion [PLB 774 (2017) 522] that purely- nuclei provide the absolute minimum energy in charge-neutral baryon matter for baryon-number , is…
