Inference of the low-energy constants in Δ-full chiral effective field theory including a correlated truncation error

Isak Svensson, Andreas Ekström, and Christian Forssén

Phys. Rev. C 109, 064003 (2024) - Published 18 June, 2024

A chiral effective field theory (EFT) description of the nuclear interaction contains a power counting to organize the order-by-order contributions of the strong-interaction dynamics to nuclear observables. The truncation of the EFT expansion at finite order induces errors in predicted nucleon-nucleon scattering observables. These errors are correlated across scattering energies and angles, which robust uncertainty quantification needs to account for. This work reports a Bayesian analysis for neutron-proton scattering in a so-called Δ-full version of chiral EFT. The authors employ Gaussian processes to learn about the correlation structure of the truncation errors and find that the effective number of neutron-proton scattering data is reduced by approximately a factor of 4 due to the correlation structure of the EFT truncation error (shown in the figure for differential cross sections). The results are important for analyzing the predictive capabilities in ab-initio nuclear theory.

Nuclear mass predictions using machine learning models

Esra Yüksel, Derya Soydaner, and Hüseyin Bahtiyar

Phys. Rev. C 109, 064322 (2024) - Published 25 June, 2024

Understanding nuclear properties away from the stability line and near the limits of the nuclear landscape relies heavily on theoretical calculations, because many unstable nuclei are difficult to reach in experiments. The authors apply two machine learning (ML) models to assess their performance in predicting nuclear mass excesses using available experimental data and a physics-based feature space. The models successfully reproduce known physical relationships and demonstrate a robust capability for extrapolation far beyond the training and test regions, offering results comparable to the model calculations. Incorporating techniques that enhance the interpretability of the ML models highlights their potential as powerful nuclear physics tools.

Microscopic optical potential from the relativistic Brueckner-Hartree-Fock theory: Proton-nucleus scattering

Pianpian Qin, Sibo Wang, Hui Tong, Qiang Zhao, Chencan Wang, Z. P. Li, and Peter Ring

Phys. Rev. C 109, 064603 (2024) - Published 3 June, 2024

Microscopic optical potentials based on realistic nucleon-nucleon interactions are important for describing the scattering phenomenology involving nuclei far away from the valley of nuclear stability. The authors construct a new optical potential by combining the relativistic Brueckner-Hartree-Fock theory with a microscopic description of the density profile of the target nucleus. The new model provides good reproduction of proton scattering data on five target nuclei, opening up interesting perspectives for applications to exotic nuclei, including setting up a reliable framework to investigate isospin effects in nuclear structure from a scattering perspective.

Bayesian quantification of strongly interacting matter with color glass condensate initial conditions

Matthew Heffernan, Charles Gale, Sangyong Jeon, and Jean-François Paquet

Phys. Rev. C 109, 065207 (2024) - Published 20 June, 2024

The authors perform rigorous Bayesian inference on a variety of measurements in relativistic Pb-Pb collisions at the LHC using a comprehensive multistage model combining QCD-based initial states with viscous hydrodynamics and a hadronic afterburner. In particular, they extracted systematic constraints on the temperature dependence of shear and bulk viscosities of quark-gluon plasma that are significantly more precise due to improved physical models and statistical methods. For the range of plasma temperature probed in heavy-ion collisions, they find that the specific bulk viscosity demanded by the data is strongly non-zero and temperature-dependent, whereas the specific shear viscosity shows a much weaker temperature dependence that is indistinguishable from a constant value even with improved statistical analysis. Importantly, the authors showcase the application of transfer learning to efficiently explore a range of model uncertainties wider than had been considered previously. This work represents a substantial advancement in constraining the shear and bulk viscosities of strongly interacting matter.

Structure in the speed of sound: From neutron stars to heavy-ion collisions

Nanxi Yao, Agnieszka Sorensen, Veronica Dexheimer, and Jacquelyn Noronha-Hostler

Phys. Rev. C 109, 065803 (2024) - Published 17 June, 2024

Properties of neutron stars such as their masses and radii arise from the characteristics of highly asymmetric nuclear matter (with many more neutrons than protons) which is not accessible in experiments. The authors consider a family of neutron-star equations of state characterized by a nontrivial behavior of nuclear matter at high densities, including a steep rise and then decline (i.e., a sharp peak) in the speed of sound with density, which is compatible with ultraheavy neutron stars up to 2.5 solar masses. The symmetry-energy expansion is then applied to obtain equations of state applicable to the almost symmetric nuclear matter created in heavy-ion collisions in the laboratory. The authors find that the description incorporating a sharp peak in the speed of sound profile aligns well with experimental data. The systematic approach opens promising perspectives for further investigations bridging the physics of neutron stars and heavy-ion collisions.

Superfluid extension of the self-consistent time-dependent band theory for neutron star matter: Anti-entrainment versus superfluid effects in the slab phase

Kenta Yoshimura and Kazuyuki Sekizawa

Phys. Rev. C 109, 065804 (2024) - Published 17 June, 2024

This work studies the structure and dynamics of the inner crust of neutron stars where nuclear matter is expected to form slabs or so-called pasta phases. The authors report a first fully self-consistent calculation of the structure of the Coulomb lattice of nuclei immersed in a sea of dripped neutrons, taking fully into account, and on the same footing, both the band structure and superfluid effects. They employ a real-time method to extract the collective masses of a slab and of protons, which in turn quantify the conduction-neutron number density and the neutron effective mass, known as the entrainment effect. The results agree with recent self-consistent band calculations without superfluidity and demonstrate that the neutron effective mass is substantially reduced up to about 42% in the slab phase; superfluidity slightly enhances this anti-entrainment effect. The current one-dimensional formalism can be extended to two and three dimensions once the computational challenges of parallelization have been successfully addressed. This gives hope that the controversial situation concerning the entrainment effects in the inner crust of neutron stars can be resolved.

Phys. Rev. C 109, 065207 (2024) - Published 20 June, 2024

The authors perform rigorous Bayesian inference on a variety of measurements in relativistic Pb-Pb collisions at the LHC using a comprehensive multistage model combining QCD-based initial states with viscous hydrodynamics and a hadronic afterburner. In particular, they extracted systematic constraints on the temperature dependence of shear and bulk viscosities of quark-gluon plasma that are significantly more precise due to improved physical models and statistical methods. For the range of plasma temperature probed in heavy-ion collisions, they find that the specific bulk viscosity demanded by the data is strongly non-zero and temperature-dependent, whereas the specific shear viscosity shows a much weaker temperature dependence that is indistinguishable from a constant value even with improved statistical analysis. Importantly, the authors showcase the application of transfer learning to efficiently explore a range of model uncertainties wider than had been considered previously. This work represents a substantial advancement in constraining the shear and bulk viscosities of strongly interacting matter.

Properties of neutron stars such as their masses and radii arise from the characteristics of highly asymmetric nuclear matter (with many more neutrons than protons) which is not accessible in experiments. The authors consider a family of neutron-star equations of state characterized by a nontrivial behavior of nuclear matter at high densities, including a steep rise and then decline (i.e., a sharp peak) in the speed of sound with density, which is compatible with ultraheavy neutron stars up to 2.5 solar masses. The symmetry-energy expansion is then applied to obtain equations of state applicable to the almost symmetric nuclear matter created in heavy-ion collisions in the laboratory. The authors find that the description incorporating a sharp peak in the speed of sound profile aligns well with experimental data. The systematic approach opens promising perspectives for further investigations bridging the physics of neutron stars and heavy-ion collisions.

Superfluid extension of the self-consistent time-dependent band theory for neutron star matter: Anti-entrainment versus superfluid effects in the slab phase

Phys. Rev. C 109, 065804 (2024) - Published 17 June, 2024

This work studies the structure and dynamics of the inner crust of neutron stars where nuclear matter is expected to form slabs or so-called pasta phases. The authors report a first fully self-consistent calculation of the structure of the Coulomb lattice of nuclei immersed in a sea of dripped neutrons, taking fully into account, and on the same footing, both the band structure and superfluid effects. They employ a real-time method to extract the collective masses of a slab and of protons, which in turn quantify the conduction-neutron number density and the neutron effective mass, known as the entrainment effect. The results agree with recent self-consistent band calculations without superfluidity and demonstrate that the neutron effective mass is substantially reduced up to about 42% in the slab phase; superfluidity slightly enhances this anti-entrainment effect. The current one-dimensional formalism can be extended to two and three dimensions once the computational challenges of parallelization have been successfully addressed. This gives hope that the controversial situation concerning the entrainment effects in the inner crust of neutron stars can be resolved.
