Parameter-independent predictions for nuclear shapes and B(E2) transition rates in the proxy-SU(3) model

A. Martinou, S. Peroulis, D. Bonatsos +6

Using a new approximate analytic parameter-free proxy-SU(3) scheme, we make predictions of shape observables for actinides and superheavy elements, namely beta and gamma deformatio…

A new scheme for heavy nuclei: proxy-SU(3)

D. Bonatsos, R. F. Casten, A. Martinou +5

The SU(3) symmetry realized by J. P. Elliott in the sd nuclear shell is destroyed in heavier shells by the strong spin-orbit interaction. However, the SU(3) symmetry has been used…

Proxy-SU(3) symmetry in heavy nuclei: Prolate dominance and prolate-oblate shape transition

S. Sarantopoulou, D. Bonatsos, I. E. Assimakis +5

Using a new approximate analytic parameter-free proxy-SU(3) scheme, simple predictions for the global feature of prolate dominance and for the locus of the prolate-oblate shape tra…

Chiral interactions up to next-to-next-to-next-to-leading order and nuclear saturation

C. Drischler, K. Hebeler, A. Schwenk

We present an efficient Monte Carlo framework for perturbative calculations of infinite nuclear matter based on chiral two-, three-, and four-nucleon interactions. The method enabl…

Structure of the lightest tin isotopes

T. D. Morris, J. Simonis, S. R. Stroberg +7

We link the structure of nuclei around Sn, the heaviest doubly magic nucleus with equal neutron and proton numbers (), to nucleon-nucleon () and three-nucleon (…

Proton pairing in neutron stars from chiral effective field theory

Yeunhwan Lim, Jeremy W. Holt

We study the proton pairing gap in beta-equilibrated neutron star matter within the framework of chiral effective field theory. We focus on the role of three-body force…

Gamow-Teller and double-beta decays of heavy nuclei within an effective theory

Eduardo Antonio Coello Pérez, Javier Menéndez, Achim Schwenk

We study decays within an effective theory that treats nuclei as a spherical collective core with an even number of neutrons and protons that can couple to an additional neutro…

Analyzing the Fierz Rearrangement Freedom for Local Chiral Two-Nucleon Potentials

L. Huth, I. Tews, J. E. Lynn +1

Chiral effective field theory is a framework to derive systematic nuclear interactions. It is based on the symmetries of quantum chromodynamics and includes long-range pion physics…

Double-folding potentials from chiral effective field theory

V. Durant, P. Capel, L. Huth +2

The determination of nucleus-nucleus potentials is important not only to describe the properties of the colliding system, but also to extract nuclear-structure information and for…

Quantum Monte Carlo calculations of light nuclei with local chiral two- and three-nucleon interactions

J. E. Lynn, I. Tews, J. Carlson +4

Local chiral effective field theory interactions have recently been developed and used in the context of quantum Monte Carlo few- and many-body methods for nuclear physics. In this…

Dispersion and decay of collective modes in neutron star cores

D. N. Kobyakov, C. J. Pethick, S. Reddy +1

We calculate the frequencies of collective modes of neutrons, protons and electrons in the outer core of neutron stars. The neutrons and protons are treated in a hydrodynamic appro…
