From bare two-nucleon interaction to nuclear matter and finite nuclei in a relativistic framework
Shihang Shen, Jun-Xu Lu, Li-Sheng Geng +2
Understanding nuclear forces, infinite nuclear matter, and finite nuclei within a unified framework has remained a central challenge in nuclear physics for decades. While most \tex…
Nuclear matter in relativistic Brueckner-Hartree-Fock theory with local and nonlocal covariant chiral interactions at leading order
Wei-Jiang Zou, Yi-Long Yang, Shihang Shen +1
The simultaneous description for nuclear matter and finite nuclei has been a long-standing challenge in nuclear ab initio theory. With the success for nuclear matter, the relativis…
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…
Emergent geometry and duality in the carbon nucleus
Shihang Shen, Serdar Elhatisari, Timo A. Lähde +3

Wigner SU(4) symmetry, clustering, and the spectrum of C
Shihang Shen, Timo A. Lähde, Dean Lee +1
We present lattice calculations of the low-lying spectrum of C using a simple nucleon-nucleon interaction that is independent of spin and isospin and therefore invariant und…
Extended Lipkin-Meshkov-Glick Hamiltonian
