Enhancement of alpha-decay by positive hexadecapole deformation
Kai Ren, Minghui Hu, Pengfei Ma +2
Whether hexadecapole deformation () influences decay remains controversial: machine-learning analyses suggest a strong link to cluster preformation, while empirical formul…
Extracting nuclear charge radii from binding energies: a single-parameter empirical formula with structural corrections
Pengfei Ma, Minghui Hu, Kai Ren +2
Nuclear binding energies and charge radii stem from the same underlying physics: saturation, isospin dependence, shell structure, and deformation. Binding-energy data therefore pro…
Analytical penetration probability including the centrifugal potential: An improved Buck--Merchant--Perez model for alpha-decay half-lives
Minghui Hu, Pengfei Ma, Kai Ren +2
We derive a closed-form, non-perturbative WKB penetration formula for alpha-decay that explicitly incorporates the centrifugal potential within the Buck--Merchant--Perez (BMP) clus…
Long-Range Order in a Strictly Short-Range Quasi-2D XY Model: When Critical Fluctuations Matter
Minghui Hu, Chao Zhang, Dajun Zhang +3
The phase of spins in the quasi-two-dimensional (q2D) XY model has emerged as a topic of significant interest across multiple subfields of physics. Conventional wisdom, rooted in t…
