Quantum field theory is one of the most successful tools physicists use to describe the physical world. For example, the Standard Model, which describes in precise detail the behavior of all known particles, is a quantum field theory. Other quantum field theories are used to describe systems of very practical interest, superconductors and other exotic materials which lie at the core of modern and future electronic devices, such as quantum computers. Depending on the specific situation, a quantum field theory may be "weakly coupled" or "strongly coupled". Weakly coupled field theories are very well understood, and allow precise calculations which match in detail experimental results. Strongly coupled field theories are poorly understood, and very hard to use for precise calculations. This fact obstructs our progress in a variety of subjects. The main objective of this proposal is to develop new computational tools and ideas to study strongly coupled quantum field theories. Ultimately, progress in our theoretical understanding of strongly coupled field theories will impact our ability to taylor exotic quantum systems to practical applications, advance out understanding of the fundamental laws of the universe, and lead to deep mathematical advances.

量子场论是物理学家用来描述物理世界的最成功的工具之一。例如，标准模型，它精确地描述了所有已知粒子的行为，是一种量子场论。其他量子场论用于描述非常实用的系统，超导体和其他奇异材料，它们是现代和未来电子设备的核心，如量子计算机。根据具体情况，量子场论可以是“弱耦合”或“强耦合”。弱耦合场理论是非常好理解的，并允许精确的计算，详细的实验结果相匹配。人们对强耦合场论知之甚少，而且很难用于精确计算。这一事实阻碍了我们在许多问题上的进展。这个计划的主要目标是发展新的计算工具和想法来研究强耦合量子场论。最终，我们对强耦合场论的理论理解的进步将影响我们将泰勒奇异量子系统应用于实际应用的能力，推进对宇宙基本定律的理解，并导致深刻的数学进步。
