Nearly half the electricity produced in the Netherlands is now renewable
In 2023, 48 percent of electricity was generated from renewable sources such as solar, wind and water. Between May and July, over half of the electricity generated in the Netherlands was from renewable sources, and that share reached as high as 57 percent in July. Production from renewable sources increased by 21 percent in 2023 compared with the previous year. The share of electricity generated from fossil fuels fell, and the Netherlands exported more electricity to neighbouring countries than…

South Africa's new energy plan needs a mix of nuclear, gas, renewables and coal, says expert
South Africa's economy has been hard hit by 15 years of loadshedding (rolling blackouts). The country's coal-fired power plants have a maintenance backlog and frequently experience unexpected technical failures. On the other hand, South Africa has committed, under the Paris Agreement, to transition to low-carbon energy generation technologies by 2050. This puts South Africa at an energy crossroads where it needs well thought out policy development and implementation to make the transition possi…

Symmetry energy and neutron star properties constrained by chiral effective field theory calculations
We investigate the nuclear symmetry energy and neutron star properties using a Bayesian analysis based on constraints from different chiral effective field theory calculations using new energy density functionals that allow for large variations at high densities. Constraints at high densities are included from observations of GW170817 and from NICER. In particular, we show that both NICER analyses lead to very similar posterior results for the symmetry energy and neutron star properties when fo…

Mini-jet Clustering Algorithm Using Transverse-momentum Seeds in High-energy Nuclear Collisions
We propose an algorithm to detect mini-jet clusters in high-energy nuclear collisions, by selecting a high-transverse-momentum ($p_T$) particle as a seed and assigning a clustering radius ($R$) in the pseudorapidity and azimuthal-angle space. Our PYTHIA simulations for $p$+$p$ collisions show that a scheme with a seeding $p_T$ of around 0.5 GeV/$c$ and $R$ of approximately 0.6 satisfactorily identifies mini-jet clusters. The correlation between clusters obtained in PYTHIA calculations using the…

Strengthening nuclear symmetry energy constraints using multiple resonant shattering flares of neutron stars with realistic mass uncertainties
With current and planned gravitational-wave (GW) observing runs, coincident multimessenger timing of Resonant Shattering Flares (RSFs) and GWs may soon allow for neutron star (NS) asteroseismology to be used to constrain the nuclear symmetry energy, an important property of fundamental nuclear physics that influences the composition and equation of state of NSs. In this work we examine the effects of combining multiple RSF detections on these symmetry energy constraints, and consider how realis…

arXiv:2404.19599v1 Announce Type: new
Abstract: The violation of parity (P) and time-reversal (T) symmetry is enhanced in the LaS, LaO and LuO molecules due to the existence of states of opposite parity with small energy differences and the presence of heavy nuclei. We calculate the molecular enhancement for the P, T-violating electron electric dipole moment ($W_{\mathrm{d}}$), scalar-pseudoscalar nucleon-electron interaction ($W_{\mathrm{s}}$), nuclear magnetic quadrupole moment ($W_{\mathrm{M}}$), and for the nuclear spin-dependent P-violating anapole moment ($W_{\mathrm{A}}$). We use the relativistic 4-components coupled cluster method and perform a systematic study to estimate the associated uncertainties in our approach. We find that the individual contribution of each computational parameter to the total uncertainty in a system is approximately the same for all the calculated enhancement factors, summing up to a total uncertainty of $\sim7$\%. We discuss the energy shifts and matrix elements associated with the calculated molecular enhancement factors and relate them to higher-energy P- and P, T- violating interactions.

Origin of the Very High Energy γ-rays in the Low-luminosity Active Galactic Nucleus NGC 4278
NGC 4278, a Low-luminosity active galactic nucleus (AGN), is generally classified as a low-ionization nuclear emission line region (LINER) type AGN. Recently, it is reported to be associated with a very high energy (VHE) $γ$-ray source 1LHAASO J1219+2915 in the first Large High Altitude Air Shower Observatory (LHAASO) source catalog. However, no associated counterpart has been detected by Fermi-LAT. By analyzing its X-ray observation data from Swift-XRT, we find it is in a high-flux state on M…

Measurements of low energy nuclear recoil quenching factors for Na and I recoils in the NaI(Tl) scintillator
Elastic scattering off nuclei in target detectors, involving interactions with dark matter and coherent elastic neutrino nuclear recoil (CE$ν$NS), results in the deposition of low energy within the nuclei, dissipating rapidly through a combination of heat and ionization. The primary energy loss mechanism for nuclear recoil is heat, leading to consistently smaller measurable scintillation signals compared to electron recoils of the same energy. The nuclear recoil quenching factor (QF), represen…

Correlation between the symmetry energy slope and the deconfinement phase transition
We study how the nuclear symmetry energy slope ($L$) can affect the hadron-quark phase transition and neutron star properties. We show that the main physical quantities as the critical chemical potential and pressure are strongly influenced by the symmetry energy slope. In extreme cases, the total amount of deconfined quarks can reach up to 99$\%$ of the hybrid star mass.

Astromers: Status and Prospects
The extreme temperatures and densities of many astrophysical environments tends to destabilize nuclear isomers by inducing transitions to higher energy states. Those states may then cascade to ground. However, not all environments destabilize all isomers. Nuclear isomers which retain their metastable character in pertinent astrophysical environments are known as astrophysically metastable nuclear isomers, or "astromers". Astromers can influence nucleosynthesis, altering abundances or even creat…

A closer scrutiny of cosmic ray proton energy losses
The percent-level precision attained by modern cosmic ray (CR) observations motivates reaching a comparable or better control of theoretical uncertainties. Here we focus on energy-loss processes affecting low-energy CR protons ($\sim 0.1-5$ GeV), where the experimental errors are small and collisional effects play a comparatively larger role with respect to collisionless transport ones. We study three aspects of the problem: i) We quantitatively assess the role of the nuclear elastic cross-sect…

Nuclear magnetism in the deformed halo nucleus $^{31}$Ne
Based on the point-coupling density functional, the time-odd deformed relativistic Hartree-Bogoliubov theory in continuum (TODRHBc) is developed. Then the effects of nuclear magnetism on halo phenomenon are explored by taking the experimentally suggested deformed halo nucleus $^{31}$Ne as an example. For $^{31}$Ne, nuclear magnetism contributes 0.09 MeV to total binding energy, and the breaking of Kramers degeneracy results in 0-0.2 MeV splitting in canonical single-particle spectra. The blocke…

A Bayesian mixture model approach to quantifying the empirical nuclear saturation point

Although not directly measurable, the nuclear saturation point $(n_0,E_0)$ can be extrapolated by density functional theory (DFT), providing tight constraints for microscopic interactions derived from chiral effective field theory (E…

The chiral ward identity connects the in-medium quark condensate to the soft limit value of the pseudoscalar correlation function evaluated in nuclear matter. The in-medium correlation function of the psuedoscalar fields with strangeness describes in-medium kaon propagation and is obtained by kaon-nucleon scattering amplitudes in the low density approximation.

The terrestrial data, spans from bulk properties of finite nuclei to the heavy-ion collisions, constrain the symmetric nuclear matter EoS and the symmetry energy up to twice the saturation density ($ρ_0$= 0.16 fm$^{-3}$).

Radiative corrections to the spin asymmetry in elastic polarized electron - nucleus collisions at high energy
Improving the numerical precision, dispersion corrections to the beam-normal spin asymmetry which arise from the dominant nuclear excitations, are estimated up to a collision energy of 1 GeV. A nonperturbative calculation of vacuum polarization and the vertex plus self-energy correction, using optimized potentials, indicates that for small scattering angles both these quantum electrodynamical (QED) effects on the spin asymmetry decrease with energy above 200 MeV and can mostly be neglected at h…

Nuclear Matter Equation of State in the Brueckner-Hartree-Fock Approach and Standard Skyrme Energy-Density Functionals
The equation of state of asymmetric nuclear matter as well as the neutron and proton effective masses and their partial-wave and spin-isospin decomposition are analyzed within the Brueckner--Hartree--Fock approach. Theoretical uncertainties for all these quantities are estimated by using several phase-shift-equivalent nucleon-nucleon forces together with two types of three-nucleon forces, phenomenological and microscopic. It is shown that the choice of the three-nucleon force plays an important…

Investigation of the determination of nuclear deformation using high-energy heavy-ion scattering
Background: Nuclear deformation provides a crucial characteristic of nuclear structure. Conventionally, the quadrupole deformation length of a nucleus, $δ_{2}$, has often been determined based on a macroscopic model through a deformed nuclear potential with the deformation length $δ^{\rm (pot)}_{2}$, which is determined to reproduce the nuclear scattering data. This approach assumes $δ_{2}=δ^{\rm (pot)}_{2}$ although there is no theoretical foundation. Purpose: We clarify the relationship b…

Supernova explosions are the most powerful neutrino sources. The neutrino emission is also the dominating cooling mechanism for a proto-neutron star, whose interior is mainly composed of extremely dense and hot nuclear matter. Neutrino transport is an essential part of the simulation of these phenomena, and modern codes are able to implement inelastic neutrino scattering and also to some extent its angle distribution. We therefore study the energy and angle dependence of neutrino scattering rat…

The two most important contributions to the deformation energy have their origin in shell effects and the surface energy coefficient of nuclear matter.
