Our aim is to engineer the properties of ultracold atoms, and molecules, in optical lattices and so use these precisely controlled many-body systems to model important strongly-correlated systems from Condensed Matter Physics (CMP). Optical-lattice experiments thus function as ‘analogue’ quantum computers, and allow exploration of physical regimes inaccessible in CMP systems themselves. The ultimate vision is to develop a complete ‘toolbox’ of methods for the direct quantum simulation (DQS) of strongly-correlated systems. The intense current interest in this powerful interdisciplinary approach to fundamental quantum many-body problems has been stimulated, in part, by work carried out by members of this CRP. For example, Professor Bloch played a leading role in the first experimental observation of the superfluid to Mott Insulator transition in an optical lattice, a prime example of modelling CMP in such systems. This was predicted theoretically by Dr Jaksch (while working with Professor Zoller in Innsbruck). These ideas were recently extended in Florence to controlled disorder in optical lattices, and production of a Bose glass phase.This CRP will stimulate further work and collaborations between theory and experiment. The ground-breaking work on disorder will be continued by Dr Fort, using both bosons and fermions, and including time-dependent studies. Professor Foot’s team (Oxford) will create a rotating optical lattice to simulate the application of a magnetic field to the analogous Condensed Matter system, and test predictions of Dr. Jaksch on the high-field Fractional Quantum Hall Effect. Professor Bloch’s group (Mainz) will create heteronuclear dipolar molecules in an optical lattice and exploit their strong electrostatic interactions for DQS of spin systems. The theory groups of Dr. Jaksch in Oxford and Dr. Daley in Innsbruck, will use state-of-the-art techniques to model the experimental systems, studying , e.g., time-dependent transport phenomena and methods for preparing specialised many-body states via controlled addition of noise.

我们的目的是在光学晶格中设计超电原子和分子的性能，因此使用这些精确控制的多体系统来对重要的强烈相关系统（CMP）进行建模。因此，光学实验实验充当“模拟”量子计算机，并允许探索在CMP系统本身中无法访问的物理状态。最终的视觉是为强相关系统的直接量子模拟（DQS）开发完整的“工具箱”。当前对这种强大的跨学科方法对基本量子多体问题的强烈兴趣是通过该CRP成员所做的工作刺激的。例如，布洛赫教授在对莫特绝缘体过渡的第一个实验性观察中发挥了领导作用，这是对这种系统中CMP建模的一个典型示例。这是雅克斯博士（Jaksch）博士（在因斯布鲁克（Innsbruck）与Zoller教授一起工作时）的理论。这些想法最近在佛罗伦萨扩展到光学晶格中的受控疾病，并产生了玻色玻璃相。这种CRP将刺激理论与实验之间的进一步工作和合作。 Fort博士将使用玻色子和费米子继续进行关于疾病的开创性工作，并包括时间依赖性研究。 Foot教授的团队（牛津）将创建一个旋转的光学晶格，以模拟磁场在类似的冷凝物质系统中的应用，并测试Jaksch博士在高场分数量子厅效应中的预测。 Bloch教授组（MAINZ）将在光学晶格中创建异核偶性分子，并利用其强静电相互作用用于自旋系统的DQS。牛津大学雅克斯博士的理论组和因斯布鲁克（Innsbruck）的戴利（Daley）博士将使用最先进的技术来对实验系统进行建模，例如，研究，例如时间依赖的运输现象和方法，通过受控的噪声来制备专业的多体状态。
