Development and Validation of the GEANT4 Model of the Electron Proton Helium Instrument on Board the SOHO Spacecraft Utilizing the Accelerator Measurements at the Hahn‐Meitner Institute Berlin

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Context. The Electron Proton Helium INstrument (EPHIN) aboard SOlar and Heliospheric Observatory is a particle telescope that measures energetic protons and helium above 4 MeV/nuc and electrons above 150 keV. While a calibration of EPHIN has been performed before launch, it has only partially been assessed reducing the accuracy of the detector

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, Volume 8, Issue 12, December 2025.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Family of chiral two- plus three-nucleon interactions for accurate nuclear structure studies

Physics Letters B, 2020
We present a family of nucleon-nucleon (NN) plus three-nucleon (3N) interactions up to N3LO in the chiral expansion that provides an accurate ab initio description of ground-state energies and charge radii up to the medium-mass regime with quantified ...

Emerging Concepts in Nuclear Structure Based on the Shell Model

Physics, 2022
Some emerging concepts of nuclear structure are overviewed. (i) Background: the many-body quantum structure of atomic nucleus, a complex system comprising protons and neutrons (called nucleons collectively), has been studied largely based on the idea of ...

Generative Modeling of Nucleon-Nucleon Interactions

Physical Review Letters
Developing high-precision models of the nuclear force and propagating the associated uncertainties in quantum many-body calculations of nuclei and nuclear matter remain key challenges for ab initio nuclear theory. In the present work we demonstrate that generative machine learning models can construct novel instances of the nucleon-nucleon interaction ...

Vortex beam nanofocusing and optical skyrmion generation via hyperbolic metamaterials

Nanophotonics, Volume 14, Issue 25, Page 4545-4553, December 2025.
Abstract While spin angular momentum is limited to ±ℏ, orbital angular momentum (OAM) is, in principle, unbounded, enabling tailored optical transition rules in quantum systems. However, the large optical size of vortex beams hinders their coupling to nanoscale platforms such as quantum emitters. To address this challenge, we experimentally demonstrate

Deep‐subwavelength resolution detection of polar magnetization by optical spin meron lattices on hyperbolic metamaterials

Nanophotonics, Volume 14, Issue 24, Page 4323-4331, December 2025.
Abstract Magnetic‐optical Kerr or Faraday effects have been widely used to measure magnetic domain structures by analyzing far‐field polarization properties, with resolution limited by the wavelength scale of light. Here, we propose a methodology to measure the magnetic domain at a deep‐subwavelength scale by investigating the interactions between a ...

Recent Developments in Few-Nucleon Scattering

EPJ Web of Conferences, 2010
Using modern nucleon-nucleon interactions in the description of the A = 3, 4 nuclei, it is not possible to reproduce both the three- and four-nucleon binding energies simultaneously.

Charge dependence of the nucleon-nucleon interaction [PDF]

Physical Review C, 1998
Based upon the Bonn meson-exchange-model for the nucleon-nucleon ($NN$) interaction, we calculate the charge-independence breaking (CIB) of the $NN$ interaction due to pion-mass splitting. Besides the one-pion-exchange (OPE), we take into account the $2 $-exchange model and contributions from three and four irreducible pion exchanges. We calculate the

Measurement of microdosimetric spectra of high‐LET particle beams using the ENCORE detector

Medical Physics, Volume 52, Issue 11, November 2025.
Abstract Background Heavy ion radiotherapy offers distinct advantages over conventional treatments due to its superior dose distribution and enhanced biological effectiveness. However, the microdosimetric characteristics of high linear energy transfer (LET) ions, particularly near the Bragg peak, remain poorly characterized.
