Research in quantum mechanics - the physics of matter at the atomic scale – fosters the discovery of new materials with extraordinary properties. The new classes of "quantum materials" have functionalities of great interest to society. They fuel the next generation of quantum technologies. New high-temperature superconductors are used for the energy transmission and the development of ultra-powerful magnets. New metal and semiconductors allow for new kinds of electronics, sustainable energy storage, and the next generation of computers. The discovery of these materials requires a new phase of exploration of the periodic table of elements. This is a challenging task because the parameter space of materials with complex chemistry is vast; and materials with the desired properties lie hidden in far corners of this space. This project brings together ten networks of experimental, computational, and theoretical scientists from across the globe. The researchers combine their expertise and knowledge to address this challenge. Working together, they can explore a much larger parameter space. By sharing knowhow while avoiding duplication, they accelerate the quest for new quantum materials. This Project also promotes the training of a new generation of scientists with broader, practical materials-discovery oriented research.The AccelNet teams bring together quantum-material communities from across the globe to synergistically work on new families of materials. They seek to explore, along new tracts of the periodic table, the deep links between materials phenomena, quantum entanglement, topology, and emergence. This AccelNet network of networks includes complimentary networks from the USA, Canada, the UK, Japan, and the European Union. Advances in the science of quantum materials are driven by progress in synthesis and characterization techniques and the discovery of new families of superconductors, insulators, strange metals, and quantum criticality. Yet, the field is hindered by a lack of coordination, which results in a tendency to cluster around the same subset of materials. This project is organized along three parallel tracks: (i) a synthesis track, (ii) a spectroscopy track, and (iii) an extreme conditions track. International collaborative teams work on synthesizing new quantum materials. They study them by a variety of spectroscopic tools. They subject them to extreme conditions such as high pressures or magnetic fields. This new level of cooperation accelerates discoveries in the field and leads to a materials database of successes and failures, a roadmap for future research. This project is funded by the Office of International Science and Engineering (OISE).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.

量子力学的研究-原子尺度上的物质物理学-促进了具有非凡性质的新材料的发现。这种新型的“量子材料”具有令社会极感兴趣的功能。它们为下一代量子技术提供动力。新型高温超导体被用于能量传输和超强磁体的开发。新的金属和半导体允许新类型的电子产品、可持续的能量存储和下一代计算机。要发现这些物质，就需要对元素周期表进行新的探索。这是一项具有挑战性的任务，因为具有复杂化学结构的材料的参数空间是巨大的；而具有所需性质的材料隐藏在这个空间的遥远角落。这个项目汇集了来自全球的十个实验、计算和理论科学家网络。研究人员结合他们的专业知识来应对这一挑战。通过合作，他们可以探索更大的参数空间。通过在避免重复的同时分享技术诀窍，他们加速了对新量子材料的探索。该项目还促进了对具有更广泛、实用的材料发现导向研究的新一代科学家的培训。AccelNet团队将来自全球各地的量子材料社区聚集在一起，在新材料家族上协同工作。他们试图沿着元素周期表的新轨迹，探索材料现象、量子纠缠、拓扑和出现之间的深层联系。该AccelNet网络包括来自美国、加拿大、英国、日本和欧盟的免费网络。量子材料科学的进步是由合成和表征技术的进步以及新的超导体、绝缘体、奇异金属和量子临界性的发现推动的。然而，这一领域受到缺乏协调的阻碍，这导致了一种聚集在同一材料子集周围的倾向。该项目沿着三个平行的轨道组织：(I)合成轨道，(Ii)光谱轨道，和(Iii)极端条件轨道。国际合作团队致力于合成新的量子材料。他们通过各种光谱工具对它们进行研究。它们会将它们置于高压或磁场等极端条件下。这种新的合作水平加速了该领域的发现，并导致了一个关于成功和失败的材料数据库，这是未来研究的路线图。该项目由国际科学与工程办公室(OISE)资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
