0138115MansonDescription: This award supports a US-India collaboration entitled Relativistic Effects in the Photoionization of Free and Confined Atoms. US PI Steven Manson, Georgia State University (GSU) and Pranawa Deshmukh, Indian Institute of Technology (IIT), Madras will continue to develop theoretical methodologies and perform calculations that explore ionizing collisions of electromagnetic radiation with atoms and ions. They will develop the relativistic random phase approximation (RRPA) methodology and apply it to a number of diverse problems in the area of ionization of free and confined atoms and ions by electromagnetic radiation. The investigators will work closely with experimental groups to insure quantitative accuracy of the newly developed methodologies. Scope: This research will provide further insight into the nature of fundamental atomic processes. By extending atomic theory methodology to confined atoms, the PI brings the expertise of atomic physics to bear on the broader fields of chemistry and condensed matter. Additionally, greater understanding of the properties of confined atoms may yield insight into the new physics of a largely unexplored area and possibly to the development of a whole new class of devices. The PIs have a highly productive collaboration and many joint publications to their credit. This project will enable a US graduate student to do research at the Indian collaborating institution and will contribute to internationalizing students at both universities. Additionally, it will facilitate the build-up of an internationally competitive research program at the IIT, Madras.

MansonDescription：该奖项支持美印合作，题为《自由原子和受限原子光致电离中的相对论效应》。美国乔治亚州立大学(GSU)的Pi Steven Manson和印度理工学院(IIT)的Pranawa Deshmukh将继续开发理论方法并进行计算，以探索电磁辐射与原子和离子的电离碰撞。他们将发展相对论随机相位近似(RRPA)方法，并将其应用于电磁辐射电离自由和约束原子和离子领域的许多不同问题。研究人员将与实验小组密切合作，以确保新开发的方法的定量准确性。范围：这项研究将提供对基本原子过程本质的进一步洞察。通过将原子理论方法论扩展到受限原子，PI将原子物理的专业知识应用于更广泛的化学和凝聚态领域。此外，更多地了解受限原子的性质可能会使人们深入了解一个基本上未被探索的领域的新物理学，并可能开发出一种全新的设备。私人投资机构进行了卓有成效的合作，并出版了许多联合出版物，这是值得称赞的。该项目将使一名美国研究生能够在印度合作机构进行研究，并将为两所大学的学生国际化做出贡献。此外，它还将促进在马德拉斯IIT建立一个具有国际竞争力的研究项目。
