论文摘要
在本文中，我们采用了相对论多体理论，从理论上评估了TLF+分子离子在其基础状态下对电子电偶极矩搜索的适用性。为此，我们使用配置相互作用和具有高质量基础的耦合群集方法计算了有效电场的值以及分子永久电偶极矩，然后分析电子相关在所考虑属性中的作用。我们发现，TLF+具有大约163 GV/cm的有效电场价值，该电场大约比HGF和HGH分子大的一半半倍，该分子已知在非渗出系统中具有最大的有效电场。
In this article, we have employed relativistic many-body theory to theoretically assess the suitability of TlF+ molecular ion in its ground state for electron electric dipole moment searches. To that end, we have computed values of the effective electric field as well as the molecular permanent electric dipole moment using both configuration interaction and coupled cluster methods with high quality basis sets, followed by an analysis on the role of electron correlation in the considered properties. We find that TlF+ has a large value of effective electric field of about 163 GV/cm, which is about one and a half times larger than the HgF and HgH molecules, which are known to have the largest effective electric fields among non-superheavy systems.
