This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Quantum spin systems are an important topic in condensed-matter, statistical and mathematical physics, and form basic building blocks in quantum information science. This ultracold-atomic physics project focuses on the implementation of quantum spin-1/2 systems using arrays of coupled two-state atoms in an optical lattice with tunable parameters. The main goal of the project is an investigation of equilibrium phases and spin dynamics in this atomic system, based on the development of a tool for the preparation of arbitrary initial spin configurations. The project will be carried out with a Bose-Einstein condensate of rubidium-87 atoms. The realization of quantum spin systems with precisely controllable parameters can be expected to have broad scientific and technological impact. The project will advance the state of the art in the manipulation of strongly correlated quantum gases, and it will also provide scientific and technical training to both graduate and undergraduate students who will gain proficiency in the enabling technologies of lasers and optics, ultrahigh vacuum, and electronics. In conjunction with the project, the PI is developing a graduate-level course on ultracold quantum gases which will include laboratory visits and demonstrations.

该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。Quantum Spin Systems是凝结，统计和数学物理学的重要主题，并在量子信息科学中形成了基本构建基础。这个超低原子物理项目的重点是使用具有可调参数的光学晶格中的耦合两态原子的阵列实现量子自旋1/2系统。 该项目的主要目标是根据制备任意初始旋转构型的工具的开发，研究了该原子系统中平衡阶段和自旋动力学的研究。该项目将使用Rubidium-87原子的Bose-Einstein冷凝物进行。可以预期，具有准确控制参数的量子自旋系统具有广泛的科学和技术影响。该项目将在操纵密切相关的量子气体方面推进最新技术的状态，并且还将为研究生和本科生提供科学和技术培训，这些培训将熟练掌握激光和光学，Ultrahigh真空的能力，以及电子产品。与该项目结合使用，PI正在开发有关超低量子气体的研究生级课程，其中包括实验室就诊和示范。
