Lattice effective field theory for nuclei from A = 4 to A = 28

Timo A. Lähde, Evgeny Epelbaum, Hermann Krebs +3

We present an overview of the extension of Nuclear Lattice Effective Field Theory simulations to the regime of medium-mass nuclei. We focus on the determination of the ground-state…

Emergent Collectivity in Nuclei and Enhanced Proton-Neutron Interactions

Dennis Bonatsos, S. Karampagia, R. B. Cakirli +3

Enhanced proton-neutron interactions occur in heavy nuclei along a trajectory of approximately equal numbers of valence protons and neutrons. This is also closely aligned with the…

Dominant Secondary Nuclear Photoexcitation with the X-ray Free Electron Laser

Jonas Gunst, Yuri A. Litvinov, Christoph H. Keitel +1

The new regime of resonant nuclear photoexcitation rendered possible by x-ray free electron laser beams interacting with solid state targets is investigated theoretically. Our resu…

Effective Field Theory for Finite Systems with Spontaneously Broken Symmetry

T. Papenbrock, H. A. Weidenmueller

We extend effective field theory to the case of spontaneous symmetry breaking in genuinely finite quantum systems such as small superfluid systems, molecules or atomic nuclei, and…

Nuclear Level Densities at High Excitation Energies and for Large Particle Numbers

Adriana Pálffy, Hans A. Weidenmüller

Starting from an independent-particle model with a finite and arbitrary set of single-particle energies, we develop an analytical approximation to the many-body level density $ρ_A(…

Nuclear Masses and Neutron Stars

Susanne Kreim, Matthias Hempel, David Lunney +1

Precision mass spectrometry of neutron-rich nuclei is of great relevance for astrophysics. Masses of exotic nuclides impose constraints on models for the nuclear interaction and th…

A new scheme of causal viscous hydrodynamics for relativistic heavy-ion collisions: A Riemann solver for quark-gluon plasma

Yukinao Akamatsu, Shu-ichiro Inutsuka, Chiho Nonaka +1

In this article, we present a state-of-the-art algorithm for solving the relativistic viscous hydrodynamics equation with the QCD equation of state. The numerical method is based o…
