Studies of atomic quantum spin systems in optical lattices

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。量子自旋系统是凝聚态，统计和数学物理学中的一个重要课题，并形成量子信息科学的基本组成部分。这个超冷原子物理学项目的重点是量子自旋1/2系统的实现，使用耦合的双态原子在一个光学晶格与可调参数的阵列。 该项目的主要目标是在开发用于制备任意初始自旋配置的工具的基础上，研究该原子系统中的平衡相和自旋动力学。该项目将使用铷-87原子的玻色-爱因斯坦凝聚体进行。实现参数精确可控的量子自旋系统预计将产生广泛的科学和技术影响。该项目将推进强相关量子气体操纵的最新技术水平，还将为研究生和本科生提供科学和技术培训，使他们能够熟练掌握激光和光学，真空和电子技术。与该项目相结合，PI正在开发一个关于超冷量子气体的研究生课程，其中包括实验室参观和演示。

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.
