This Materials World Network (MWN)/Inter-American Materials Collaboration project expands and deepens current understanding of correlated electron behavior in a variety of low-dimensional systems, including atoms and molecules on surfaces, electrons and spins in carbon nanotubes and graphene, and excitons in semiconductor quantum dots. Efforts focus on elucidating the roles of local and global symmetries, as well as interactions with thermal baths or radiation fields, in determining properties of interest for potential applications in nanomagnetism and spintronics, in new carbon-based devices, and in quantum information. A central goal is to guide and interpret experiments involving techniques that probe local interactions with high spatial and temporal resolution. This research is carried out by combining the complementary theoretical and numerical expertise of groups at Ohio University, the University of Florida, and Oakland University in the U.S., at the Pontificia Universidade Catolica do Rio de Janeiro and the Universidad Federal Fluminense in Brazil, at the Universidad Nacional de Rosario in Argentina, and at the Universidad de Antofagasta in Chile, with the non-US participants receiving support from their respective national funding agencies for their contribution. In addition to applying existing state-of-the-art methods, the team develops new techniques for the description of non-equilibrium phenomena. The project immerses young scientists in cooperative international research activities through extended visits to MWN partner institutions and participation in a mini-workshop to be held in the second year of the award. Webcasts of technical lectures across institutions will advance technical training and foster collaborations among MWN participants. The project also seeks to engage a broader audience through the development of pedagogical materials related to nanoscience. Some of this development is carried out in collaboration with students from writing and visual design programs.

这一材料世界网络(MWN)/美洲材料合作项目扩大和深化了对各种低维系统中相关电子行为的理解，包括表面上的原子和分子，碳纳米管和石墨烯中的电子和自旋，以及半导体量子点中的激子。工作的重点是阐明局部和全球对称性的作用，以及与热浴或辐射场的相互作用，确定在纳米磁学和自旋电子学、新的碳基设备和量子信息方面潜在应用感兴趣的性质。一个中心目标是指导和解释涉及以高空间和时间分辨率探测局部相互作用的技术的实验。这项研究结合了美国俄亥俄大学、佛罗里达大学和奥克兰大学、巴西里约热内卢的加多利卡大学和联邦弗卢米嫩塞大学、阿根廷的罗萨里奥国立大学和智利的安托法加斯塔大学的小组在理论和数字上的互补专长进行的，非美国参与者的捐款得到了各自国家资助机构的支持。除了应用现有最先进的方法外，该团队还开发了描述非平衡现象的新技术。该项目通过延长对MWN伙伴机构的访问和参加将在获奖第二年举行的迷你研讨会，使青年科学家沉浸在合作的国际研究活动中。跨机构的技术讲座网络广播将促进技术培训，促进MWN参与者之间的合作。该项目还寻求通过开发与纳米科学有关的教学材料来吸引更广泛的受众。其中一些开发是与来自写作和视觉设计程序的学生合作进行的。
