论文摘要
从头开始，核多体问题的方法已经在过去十年中大大延长了。但是，由于解决相应的运动方程式的高昂成本，几乎没有解决集体激励。在这里，提出了一种数值有效的方法，用于从主算的角度进行超级氟和变形核的零和有限温度的电磁响应函数，并应用于$^{16} $ o，$^{28} $^{28} $ si，$ si，$ si，$^{46} $ ti and $ ti和$ ti and $^{56} $ fe。这项工作为从核图表的很大一部分中对核对电探针的核反应进行系统的核反应开辟了道路。
Ab initio approaches to the nuclear many-body problem have seen their reach considerably extended over the past decade. However, collective excitations have been scarcely addressed so far due to the prohibitive cost of solving the corresponding equations of motion. Here, a numerically efficient method to compute electromagnetic response functions at zero- and finite-temperature in superfluid and deformed nuclei from an ab initio standpoint is presented and applied to $^{16}$O, $^{28}$Si, $^{46}$Ti and $^{56}$Fe. This work opens the path to systematic ab initio calculations of nuclear responses to electroweak probes across a significant portion of the nuclear chart.
