US-India Cooperative Research: Relativistic Effects in the Photoionization of Free and Confined Atoms

本奖项支持美印合作项目，题为“自由和受限原子光电离中的相对论效应”。美国PI Steven Manson，佐治亚州立大学（GSU）和Pranawa Deshmukh，印度理工学院（IIT），马德拉斯将继续发展理论方法和执行计算，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近似（RRPA）方法，并将其应用于电磁辐射电离自由和受限原子和离子领域的许多不同问题。研究人员将与实验组密切合作，以确保新开发方法的定量准确性。范围：这项研究将进一步深入了解基本原子过程的本质。通过将原子理论方法扩展到受限原子，PI将原子物理学的专业知识应用到更广泛的化学和凝聚态物质领域。此外，更深入地了解受限原子的性质，可能会对一个很大程度上尚未开发的领域的新物理学产生深刻的见解，并可能开发出一类全新的设备。ppi之间的合作非常富有成效，并发表了许多联合出版物。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，并将有助于两所大学的学生国际化。此外，它将促进马德拉斯印度理工学院建立一个具有国际竞争力的研究项目。

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.
