This award provides funds to support students attending the INT Summer School on Lattice QCD for Nuclear Physics at the University of Washington.Unlike the three other known fundamental forces in nature, the strong force is strong at relatively low energies, and consequently it cannot be fully studied through traditional perturbative methods. Lattice gauge theory is the field in which one therefore performs calculations involving the strong force numerically by discretizing spacetime, evaluating relevant amplitudes on this discretized spacetime, and then taking the spacing associated with the spacetime lattice to zero (thereby hopefully extracting results for the full "continuum" theory). Lattice gauge theory thus not only provides us with a direct non-perturbative means of studying the strong interaction, but also enables us to understand strong-interaction dynamics at the level of precision needed in order to give meaning to upcoming collider experiments. In recent years, the techniques of lattice gauge theory have even extended beyond the strong interaction per se, becoming relevant for fields as diverse as graphene, trapped atoms, technicolor, and even quantum gravity.Despite the importance of this subject, however, there is no systematic way for students or young researchers to learn about it. Attending this event will therefore provide junior participants not only with an overall understanding of lattice gauge theory, but also with an understanding of how lattice gauge theory may be applied to the calculation of key quantities in QCD. Students who attend will also be exposed to new trends in applying lattice methods to fields such as nuclear physics, astrophysics, and Fermi gas systems.

该奖项提供资金，以支持学生参加在华盛顿大学的晶格QCD核物理INT暑期学校。与自然界中已知的其他三种基本力不同，强力在相对较低的能量下很强，因此它不能通过传统的微扰方法进行充分的研究。 格点规范理论是这样一个领域，在这个领域中，人们通过离散时空，计算这个离散时空上的相关振幅，然后将与时空格点相关的间距取为零（从而有望为完整的“连续统”理论提取结果）来进行数值计算。因此，格点规范理论不仅为我们提供了研究强相互作用的直接非微扰方法，而且使我们能够在所需的精度水平上理解强相互作用动力学，以便为即将到来的对撞机实验提供意义。近年来，格点规范理论的技术甚至已经超出了强相互作用本身，与石墨烯、被困原子、彩色甚至量子引力等不同领域相关。尽管这一主题很重要，但是，学生或年轻的研究人员没有系统的方法来了解它。因此，参加这次活动将使年轻的参与者不仅有一个全面的了解，格点规范理论，但也与如何格点规范理论可以应用于QCD中的关键量的计算的理解。参加的学生还将接触到将晶格方法应用于核物理，天体物理和费米气体系统等领域的新趋势。
