WORKSHOP: The Future of the Correlated Electron Problem Workshop

非技术摘要：经过几十年的深入研究，我们对相关电子系统的预测能力仍然很小。相关电子的问题被认为是痛苦的，因为我们需要建立强相关系统的模型来设计新材料，比如超导体。该研讨会致力于在该领域的创始人（演讲者）和早期职业研究人员（参与者）之间进行结构化的讨论。在参与者之间进行头脑风暴，以确定到目前为止没有奏效的地方，有望产生具体的新想法，有助于解决电子相关性的问题。技术摘要：非相互作用电子的模型在固体物理学的许多领域都得到了很好的建立。然而，有些材料系统的性质是由强相互作用产生的。这种强相关的系统拥有各种各样迷人的宏观现象，包括高温超导性，金属绝缘体转变，分块拓扑相和奇怪的金属相。尽管多年的密集工作，许多这些系统的基本物理仍然不被理解，我们没有一个统一的观点对强电子相关性。本次研讨会将以一种独特的形式将早期职业研究人员和一些杰出的资深科学家混合在一起，目的是在相关电子问题上取得进展。在第一天，六位对相关电子物理有广泛见解的资深科学家将为大约45位早期职业科学家进行一系列讲座。这些资深科学家将介绍他们认为相关电子问题的重要方面，以及他们认为可能的发展方向。第二天早上，高层人员将离开。然后，在第2天的一天里，早期职业科学家将围绕这一物理学进行圆桌讨论、工作组和头脑风暴会议，并阐明他们对如何取得进展的想法。这些想法将在第一天的讲座中被告知。第三天，这些早期的职业科学家将写一份报告，总结讨论的结果。报告将公开发布。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Nontechnical abstract: After decades of intensive research, our predictive power in systems with correlated electrons is still very small. The problem of correlated electrons is recognized as painful, because our ability to model strongly correlated systems is needed to design new materials such as superconductors. This workshop is devoted to enabling structured discussion between the founders of the field (speakers) and early career researchers (participants). Brainstorming between the participants in order to identify what did not work so far is expected to lead to specific novel ideas, helpful in solving the problem of electron correlations. Technical abstract: The model of non-interacting electrons is well established throughout many areas of solid-state physics. However there are material systems whose properties emerge from strong interactions. Such strongly correlated systems host a tremendous variety of fascinating macroscopic phenomena including high-temperature superconductivity, metal-insulator transitions, fractionalized topological phases, and strange metal phases. Despite many years of intensive work, the essential physics of many of these systems is still not understood, and we do not have a unified perspective on strong electron correlations. This workshop will mix — in a unique format — early career researchers and a number of distinguished senior scientists with the aim of making progress on the correlated electron problem. On Day 1, six senior scientists with broad perspectives on the correlated electron physics will give a series of lectures to approximately 45 early career scientists. These senior scientists will present what they consider to be the important aspects of the correlated electron problem and what they consider to be possible ways forward. On the morning of Day 2, the senior people will depart. Then during the day of Day 2 the early career scientists will have a number of roundtable discussions, working groups, and brainstorming sessions on this physics and clarifying their thoughts on how to make progress. These thoughts will have been informed by the lectures of Day 1. On Day 3 the early career scientists will write up a report summarizing the outcome of the discussions. Report will be publicly available.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
