Construction of Nuclear Covariant Energy Density Functional from A Physics-Guaranteed Neural Network Approach
W. F. Li, Z. M. Niu, H. Z. Liang +2
Density functional theory is a practical approach for solving quantum many-body problems with available computational resources. The complexity of the nuclear force makes construct…
From spin to pseudospin symmetry: The origin of magic numbers in nuclear structure
C. R. Ding, C. C. Wang, J. M. Yao +3
Magic numbers lie at the heart of nuclear structure, reflecting enhanced stability in nuclei with closed shells. While the emergence of magic numbers beyond 20 is commonly attribut…
Relativistic orbital-free kinetic energy density functional for one-particle nuclear systems
X. H. Wu, Z. X. Ren, H. Z. Liang +1
This letter aims to derive the exact relativistic orbital-free kinetic energy density functional for one-particle nuclear systems in one-dimensional case. The kinetic energy is exp…
Response of asymmetric nuclear matter studied with a finite number of particles
M. Li, F. Marino, G. Colò +1
We investigate the ground-state properties of asymmetric nuclear matter and its response to a static perturbation using the density functional theory framework. Our method, which e…
