WORKSHOP: The Future of the Correlated Electron Problem Workshop

非技术摘要：经过几十年的密集研究，我们对具有关联电子的系统的预测能力仍然很小。关联电子的问题被认为是痛苦的，因为我们为强关联系统建模的能力是设计新材料(如超导体)所必需的。该讲习班致力于促进该领域的创始人(发言者)和早期职业研究人员(参与者)之间的有组织的讨论。参与者之间的集思广益，以找出到目前为止没有奏效的东西，有望带来具体的新想法，有助于解决电子关联问题。技术摘要：非相互作用电子模型在固体物理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。这种强关联的系统包含了各种令人着迷的宏观现象，包括高温超导、金属-绝缘体转变、分步拓扑相和奇怪的金属相。尽管进行了多年的密集工作，但其中许多系统的基本物理仍不清楚，我们对强电子关联也没有一个统一的观点。这次研讨会将以一种独特的形式混合早期职业研究人员和一些杰出的资深科学家，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学有广泛看法的资深科学家将给大约45名早期职业科学家做一系列讲座。这些资深科学家将介绍他们认为是关联电子问题的重要方面，以及他们认为可能的前进方向。第二天上午，高级人员将离开。然后，在第二天，早期职业科学家将有许多关于这个物理的圆桌讨论、工作组和集思广益会议，并澄清他们对如何取得进展的想法。这些想法将从第一天的讲座中了解到。在第三天，早期职业科学家将写一份报告，总结讨论的结果。该奖项反映了NSF的法定使命，并通过使用基金会的学术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.
