This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The research here will center on two major themes, pursued with theoretical calculations, both numerical and analytic: (i) The first part of the work examines the time-dependence of quantum entanglement, to clarify and extend recently identified phenomena related to early-stage decoherence (ESD), also called entanglement sudden death. The PI further will examine entanglement in a system consisting of two atoms in two different cavities. The second part of the work deals with the dynamical evolution of quantum entanglement, to obtain an improved description of propagation in partially coherent optical absorbers of two competing and cooperating short pulses. The emphasis will be on ways to find analytical solutions. There will also be a workshop in the first area of the research, on Non-Markovian Relaxation and Entanglement Dynamics.Students working in this research program will receive training that will enable them to continue to work in science in academic, industrial, and governmental contexts, taking their education and their talents into a wide community.

该奖项根据 2009 年《美国复苏和再投资法案》（公法 111-5）提供资金。这里的研究将集中在两个主要主题上，并通过数值和分析的理论计算来进行： (i) 研究的第一部分检查量子纠缠的时间依赖性，以澄清和扩展最近发现的与早期退相干（ESD）（也称为纠缠猝死）相关的现象。首席研究员将进一步研究由两个不同空腔中的两个原子组成的系统中的纠缠。该工作的第二部分涉及量子纠缠的动态演化，以获得两个竞争和协作短脉冲在部分相干光吸收体中传播的改进描述。重点将放在寻找分析解决方案的方法上。该研究的第一个领域还将举办一个关于非马尔可夫弛豫和纠缠动力学的研讨会。参与该研究项目的学生将接受培训，使他们能够继续在学术、工业和政府背景下从事科学工作，将他们的教育和才能带入更广泛的社区。
