壳模型在复能量平面上的新Monte Carlo表示

Novel Monte Carlo representation for shell model in the complex energy plane

Zhen-Xiang Xu, Chong Qi

摘要:

提出了一种计算多粒子连续运动量子态的蒙特卡罗方法。散射状态在每个时间通过蒙特卡罗随机抽样算法生成。重复相同的计算,直到所有计算的平均能量收敛。对于具有一个或几个粒子的系统,我们的计算表明,只需大约一百次迭代即可接近精确解。作为例子,我们应用该方法来研究丰中子氧同位素的结构。

英文摘要:

A Monte Carlo method is presented to evaluate quantum states with many particles moving in the continuum. The scattering state is generated at each time by a Monte Carlo random sampling algorithm. The same calculation are repeated until the average energies of all calculations converge. For systems with one and a few particles, our calculations show that the exact solution can be approached with around only one hundred iterations. As examples, we apply the approach to study the structure of neutron-rich oxygen isotopes.
