Non-technical abstract: The overall goals of this program are to explore nonreciprocity in a series of Er-containing multiferroics and to invest in the education of a diverse group of young people at the University of Tennessee. Both initiatives merit broad support because they will advance the fundamental understanding of one-way transparency in ultra-low symmetry materials and contribute to important societal values and outcomes. To focus our efforts, we will concentrate on nonreciprocity in the C-band telecom regime – particularly at 1550 nm where Er glass fibers are currently in use – and several different Er-containing systems have been selected to test these ideas using high field spectroscopies at the National High Magnetic Field Laboratory. A broad range of educational, outreach, and service activities will also take place under the auspices of this National Science Foundation-funded program, especially in the areas of diversity, conference and workshop organization, and service to various national laboratories.Technical abstract: The research outlined in this proposal builds upon our team’s recent discovery of nonreciprocal directional dichroism across the telecom wavelength range in Ni3TeO6. Given the commercial use of drawn Er-glass fibers for optical communications, we hypothesize that multiferroics like Er-substituted YMnO3, Er-doped Ni3TeO6, ErFe3(BO3)4, and ErFeO3 may offer broken symmetry, low loss environments in which changing magnetic field or light propagation direction can create optical diode effects. Our goals are to (i) reveal new states of matter hosting unusual symmetries and properties, (ii) explore how ultra-low symmetries generate dynamic magnetoelectric coupling and nonreciprocity, (iii) test strategies for placing dichroic contrast in the C-band region, (iv) unravel structure-property relations connected with nonreciprocity, and (v) discover how these effects can be enhanced and controlled. What brings these efforts together is the opportunity to explore completely new types of light-matter interactions under extreme conditions. Findings from this program will advance theoretical development and photonics applications. This program also supports the interdisciplinary education of a diverse group of young researchers for future employment in academics, government laboratories, and industry in the area of quantum materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要：该计划的总体目标是探索一系列含有ER的多表情中的非交流，并投资于田纳西大学的一群年轻人的教育。这两项举措都值得广泛的支持，因为它们将提高对超低对称材料中单向透明度的基本理解，并有助于重要的社会价值和成果。为了集中精力，我们将专注于C波段电信制度中的非记录，尤其是在目前正在使用ER玻璃纤维的1550 nm时 - 选择了几种不同的含有ER的系统来使用国家高磁场实验室的高场光谱进行测试。在这个国家科学基金会资助的计划的主持下，尤其是在多样性，会议和研讨会组织的领域，以及为各种国家实验室的服务。技术摘要：该提案中的研究概述了我们团队最近在我们的非界定方向二十字内跨越telecom的ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni，这项研究摘要概述了广泛的教育，外展和服务活动。鉴于绘图ER玻璃纤维在光学通信中的商业用途，我们假设多效应诸如ER取代的YMNO3，ER兴奋剂的Ni3Teo6，Erfe3（Bo3）4（BO3）4和ERFEO3可能会提供损坏的对称性，低损失环境，在这种变化的磁场或光传播方向上会产生光学二极管效应。 Our goals are to (i) reveal new states of matter hosting unusual symmetries and properties, (ii) explore how ultra-low symmetries generate dynamic magnetoelectric coupling and nonreciprocity, (iii) test strategies for placing dichroic contrast in the C-band region, (iv) unravel structure-property relations connected with nonreciprocity, and (v) discover how these effects can be增强和控制。将这些努力融合在一起的是，有机会在极端条件下探索全新的光线相互作用。该计划的发现将推进理论开发和光子学应用程序。该计划还支持一群潜水员的年轻研究人员的跨学科教育，以在量子材料领域的学者，政府实验室和工业领域的未来就业。这项奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来通过评估来诚实地通过评估来诚实地支持。
