Hyper-Kamiokande is a next-generation underground water Cherenkov detector. Scheduled for completion in 2027, it is expected to begin data taking in 2028. Hyper-K is a multi-purpose detector designed to study neutrino oscillations, diffuse supernova neutrinos, proton decay and leptonic CP violation. With a fiducial volume eight times larger than Super-Kamiokande, and enhanced, high-efficiency...

Neutrino transport is crucial in core-collapse supernova simulations because neutrino transport effect the post-bounce evolution. In this study, we investigate the impact of modified neutrino–matter interactions in GR1D. The standard bremsstrahlung treatment is based on the Burrows et al. non-degenerate formulation, whereas neutron core in the proto-neutron star can become degenerate. We...

The Rare Isotope Accelerator complex for ON-line experiments (RAON) in Korea is poised to open a new phase in precision nuclear physics, where close interplay among theory, simulation, and experiment is essential. Because nuclear processes occur at femtometer scales and cannot be directly observed, large-scale computational simulations have become an essential component of modern experiments....

Quantum computing offers a promising route to solving many-body Hamiltonians in quantum chemistry, astrophysical molecular ions, and nuclear physics. However, as the basis set or active space grows, the configuration space increases combinatorially, making full diagonalization impractical. Variational Quantum Eigensolver approaches also face major bottlenecks from Pauli-term measurements,...

JSNS2 (J-PARC Sterile Neutrino Search at the J-PARC Spallation Neutron Source) is a neutrino oscillation experiment with 24m of baseline, targeting Δm² values near 1 eV². To investigate the LSND anomaly directly, the same neutrino source, the same neutrino target, and the same interaction are used. At the J-PARC Material and Life Science Facility, 3 GeV protons produce the neutrino beam via...

D-Wave uses so-called a quantum annealing process to solve problems of certain categories rather than universal quantum computers do. This research applies D-Wave quantum annealer to find ground state configurations of 2D Ising model. Due to its limitation in the number of qubits, D-Wave is used to update configuration of smaller sized sub-lattice, such as 4 by 4 etc., not of a whole 2D...

This study investigates charged-current (CC) neutrino-induced reactions on $^{12}\text{C}$ using mono-energetic neutrinos ($E_\nu = 236$ MeV) from kaon decay at rest (KDAR). We performed a detailed decomposition of nuclear transition strengths into spin-parity states, longitudinal and transverse components, and vector and axial-vector contributions. Our results demonstrate that KDAR neutrinos...
