摘要
以 85Rb 原子和多掺杂场为基础,构建了一个天然的非赫米特系统。在此基础上,研究了基于七阶非线性效应的四光子自发八波混合过程中,不同掺杂场对对称性破缺和能级退化的影响,并分析了四光子相关性。当掺杂拉比频率占主导地位时,实部分裂,导致同相构造掺杂,其对称性破缺是局部的、非退化的、阿贝尔的和低对称性的。当去相率占主导地位时,虚部分裂,导致相外破坏性修整,其对称性破缺是非局部、退变、非阿贝尔和高度对称的。比较了两种具有三阶 EP 的双修整效应的修整场与特征值分裂模之间的相互作用,阐明了内外修整场在三阶 EP 形成中的作用。嵌套方案的两个敷料场之间的三阶非赫米提相互作用最强,平行方案的三阶非赫米提相互作用最弱,级联方案介于两者之间。这项研究对量子态的探测和量子存储具有重要价值。
Third-order natural Non-Hermitian quantization of quad-photon Rabi oscillation in an atomic ensemble
A natural non– Hermitian system is constructed based on 85Rb atoms and multi-dressing fields. On this basis, the influence of different dressing fields on symmetry breaking and energy level degeneracy during four-photon spontaneous eight-wave mixing based on seventh-order nonlinear effects is investigated, and four-photon correlations are analyzed. When the dressing Rabi frequency dominates, the real part splits, leading to in phase constructive dressing, its symmetry breaking is localized, non-degenerate, Abelian and has low symmetry. When the dephase rate dominates, the imaginary part splits, leading to out-of-phase destructive dressing, its symmetry breaking is nonlocal, degenerate, non– Abelian and highly symmetric. The interactions between the dressing fields and the eigenvalue splitting modes of two double dressing effects that have third-order EPs are compared, and the role of the internal and external dressing fields in the formation of third-order EPs is clarified. The third-order non-Hermitian interaction between two dressing fields of the nested scheme is strongest and weakest for the parallel scheme, with the cascade scheme intermediate between them. This study is of value for the detection and quantum storage of quantum states.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
