AI中文摘要：
我们研究了利用高电荷离子检验洛伦兹对称性的前景。我们推导了与类氢离子基态中塞曼跃迁和塞曼-超精细跃迁以及类硼离子基态中塞曼跃迁和塞曼-精细跃迁相关的洛伦兹破缺能量位移。由此产生的信号包括类氢离子通过恒星频率的一次谐波以及类硼离子通过三次谐波产生的恒星时变化。对于某些其贡献随电子动量四次方标度的标准模型扩展（SME）系数，类氢离子中较大的电子动量可以在类氢离子光谱学可达到的精度下提供与现有最佳约束相竞争的灵敏度。我们还发现，类硼离子光谱学可以对某些SME系数提供有竞争力的灵敏度。
英文摘要：
We investigate the prospects for testing Lorentz symmetry using highly charged ions. We derive the Lorentz-violating energy shifts relevant to Zeeman and Zeeman-hyperfine transitions within the ground state of H-like ions and to Zeeman and Zeeman-fine transitions within the ground state of B-like ions. The resulting signals include sidereal variations through the first harmonic of the sidereal frequency for H-like ions and through the third harmonic for B-like ions. For certain SME coefficients whose contributions scale with the fourth power of the electron momentum, the large electron momentum in H-like ions can provide sensitivity competitive with the best existing bounds at the precision achievable in H-like-ion spectroscopy. We also find that B-like-ion spectroscopy can provide competitive sensitivity to certain SME coefficients.
