Neural-network excited states of A=4 nuclei and hypernuclei

Zi-Xiao Zhang, Yilong Yang, Xiao-Lu Qian, W. He et autres

We present the first variational Monte Carlo study of nuclear and hypernuclear excited states within the neural-network quantum states (NQS) framework. We implement both the overlap penalty (OP) and natural excited state (NES) methods to compute low-lying excitation spectra. To address the …

Efficient emulation of nuclear ground states with neural-network variational Monte Carlo and eigenvector continuation

Anonymous, Yilong Yang, P. W. Zhao

An efficient emulator for \emph{ab initio} calculations of nuclear ground-state properties is developed by integrating the neural-network variational Monte Carlo framework, FeynmanNet, with the eigenvector continuation. It enables the calculation of observables for different Hamiltonians with minimal computational cost, while delivering ground-state …

Intrinsic Generation of Angular Momenta and Entanglement in Fission

B. Li, D. D. Zhang, D. Vretenar, Tamara Nikšić et autres

Nuclear time-dependent density functional theory is used to investigate spin generation and entanglement of fission fragments in spontaneous fission of ^{252}Cf, incorporating both axial and nonaxial deformations. Axially symmetric fission trajectories enforce strict constraints: counterrotation (twisting mode) along the fission axis and …

Mass Probe of Tetrahedral Symmetry in Atomic Nuclei

F. F. Xu, P. W. Zhao

Tetrahedral symmetry has long been predicted as an exotic shape degree of freedom in atomic nuclei, yet clear experimental manifestations remain elusive. We show that the triple binding energy difference δV_{pn}^{(3)} can isolate a structural effect of tetrahedral symmetry in ^{80}Zr. Using …

De-excitation effects on entanglement in multi-nucleon transfer reactions

Y. C. Yang, D. D. Zhang, D. Vretenar, B. Li et autres

This study quantifies the impact of nuclear de-excitation on correlations in multi-nucleon transfer (MNT) reactions. To bridge the gap between initial collision dynamics and final experimental observables, we introduce a hybrid TDCDFT+GEMINI approach, integrating time-dependent covariant density functional theory (TDCDFT) with the …

Nonlocal Orbital-Free Density Functional Theory Incorporating Nuclear Shell Effects

Xinhui Wu, G. Colò, Kouichi Hagino, P. W. Zhao

Incorporating nuclear shell effects within the framework of orbital-free density functional theory (DFT) has remained a long-standing challenge in nuclear physics. While the Hohenberg-Kohn theorem formally guarantees the existence of an orbital-free density functional that is capable of describing all many-body effects, …

Relativistic density functional theory in 3-dimensional lattice: Fission barriers with PC-PK1

HUANG Yihan, Bo Li, P. W. Zhao

本文利用三维格点空间相对论密度泛函理论,在轴对称破缺,反射对称破缺和V4对称性破缺时,计算了锕系原子核的势能曲线,探索了所有四极和八极形变自由度对裂变内垒,外垒和同核异能态的影响.我们的计算结果表明:反射对称性破缺能显著地降低外垒的高度,轴对称性破缺能同时降低内垒和外垒的高度,V4对称性破缺对内垒和外垒几乎没有影响,同核异能态几乎不受对称性破缺的影响.基于相对论密度泛函PC-PK1和单极对相互作用的计算结果很好地再现了实验上提取的裂变内垒和外垒高度的经验值,对同核异能态的能量经验值有轻微低估.本文数据集可在https://www.doi.org/10.57760/sciencedb.j00213.00229中访问获取.(审稿阶段请通过私有访问链接查看本文数据集https://www.scidb.cn/anonymous/UVp6VUp2)
