Exploring quark mass dependent three-nucleon forces in medium-mass nuclei
Urban Vernik, Kai Hebeler, Achim Schwenk
Recently, new quark mass dependent three-nucleon (3N) forces have been identified, whose contributions in nuclear matter exceed expectations of Weinberg power-counting arguments. I…
Astrophysics equation of state inference with Bayesian chiral effective field theory uncertainties
Melissa Mendes, Hannah Göttling, Anna Hensel +5
We investigate Bayesian chiral effective field theory (EFT) uncertainties, which assign a statistical interpretation to equation of state (EOS) distributions near nuclear satur…
Neutron star crust and outer core equation of state from chiral effective field theory with quantified uncertainties
H. Göttling, L. Hoff, K. Hebeler +1
We study the order-by-order expansion of the energy per particle of asymmetric nuclear matter up to twice saturation density in chiral effective field theory (EFT) within a Bayesia…
Equation-of-state-informed pulse profile modeling
Mariska Hoogkamer, Nathan Rutherford, Daniela Huppenkothen +9
NICER has enabled mass-radius inferences for pulsars using pulse profile modeling (PPM), providing constraints on the equation of state (EOS) of cold, dense matter. To date, PPM an…
Bayesian approach for many-body uncertainties in nuclear structure: Many-body perturbation theory for finite nuclei
Isak Svensson, Alexander Tichai, Kai Hebeler +1
A comprehensive assessment of theoretical uncertainties defines an important frontier in nuclear structure research. Ideally, theory predictions include uncertainty estimates that…
Equation of state and Fermi liquid properties of dense matter based on chiral effective field theory interactions
Faruk Alp, Yannick Dietz, Kai Hebeler +1
We present results for the equation of state of symmetric nuclear matter and pure neutron matter obtained in many-body-perturbation theory (MBPT) up to third order, based on variou…
