Ground-State Energy Estimation of HeH, ArH, and HO via Sample-Based Quantum Diagonalization
Jubin Park, Chae-Hyun Yoon, Minkyu Lee +1
Accurate ground-state energies are essential for understanding molecular structure, chemical bonding, and reaction energetics in quantum chemistry. In this work, we investigate the…
Structure of multi- hypernuclei with a Skyrme-type interaction constrained by data on double- hypernuclei and neutron stars
Yusuke Tanimura, Chang Ho Hyun, Myung-Ki Cheoun
The paper studies how repulsive p‑wave and density‑dependent components of a Skyrme‑type ΛΛ interaction affect the structure of multi‑Λ hypernuclei, using spherical Hartree‑Fock ca…
Charge-symmetry-breaking effects on displacement energies and charge radius differences in mirror nuclei
Myeong-Hwan Mun, Kyoungsu Heo, Jubin Park +2
We study the effect of charge symmetry breaking (CSB) energy density function (EDF) on the mirror displacement energies (MDEs) and charge radius differences of mirror nuclei within…
Kaon-induced production off the proton
Sang-Ho Kim, Myung-Ki Cheoun
We investigate the reaction mechanism of within a hybrid Regge approach based on effective Lagrangians. The nonresonant background includes Reggeized -channel…
Electron-capture rates in the medium-mass nuclei Ti, Ni, Zn, and Ge within deformed quasiparticle random-phase approximation
Eunja Ha, Myung-Ki Cheoun, H. Sagawa +2
Electron-capture (EC) rates in medium-mass nuclei are governed by Gamow--Teller (GT) strength distributions and provide important input for stellar weak-interaction processes. In t…
Accuracy and Applicability of the Hartle-Thorne and Komatsu-Eriguchi-Hachisu Methods for Modeling Rotating Neutron Stars
Hyukjin Kwon, Kenta Yoshimura, Tsuyoshi Miyatsu +2
Neutron stars, which are composed of extremely dense nuclear matter, serve as natural laboratories to study nuclear interactions beyond the terrestrial experiments. Recent research…
