Universal Properties of Near-Threshold Single-Neutron Resonances
Myungkuk Kim, Young-Ho Song, Hans-Werner Hammer +3
We establish universal width predictions for near-threshold single-neutron resonances in partial waves. Our results go beyond Wigner's well-known scaling behavior of cross…
The compact neutron star in 4U 1746-37 revisited: Reassessing the mass and radius
Kwang Hyun Sung, Myungkuk Kim, Young-Min Kim +2
A recent analysis of photospheric radius expansion X-ray bursts from the low-mass X-ray binary 4U 1746-37 reported unusually small mass and radius estimates for the neutron star, s…
Ab Initio Calculations of the Carbon and Oxygen Isotopes: Energies, Correlations, and Superfluid Pairing
Young-Ho Song, Myungkuk Kim, Youngman Kim +5
We perform \textit{ab initio} nuclear lattice calculations of the neutron-rich carbon and oxygen isotopes using high-fidelity chiral interactions. We find good agreement with the o…
Wavefunction matching for solving quantum many-body problems
Serdar Elhatisari, Lukas Bovermann, Yuanzhuo Ma +15
Ab initio calculations play an essential role in our fundamental understanding of quantum many-body systems across many subfields, from strongly correlated fermions to quantum chem…
