Michael is beginning his research by making an addition to Grid (the Lattice QCD code used by RBC-UKQCD) to implement distillation, which is a numeric approximation in the construction of meson fields and hence n-point correlation functions which delivers speed and convergence improvements by calculating with only the most significant eigenvectors of the inverse of the Dirac matrix. The intention is to apply distillation to heavy-light quark decays, in order to obtain a signal earlier in the simulation, prior to loss of signal to noise (as currently occurs).

迈克尔开始他的研究，除了网格（RBC-UKQCD使用的格点QCD代码）来实现蒸馏，这是介子场的构造中的数值近似，因此n点相关函数通过仅计算狄拉克矩阵的逆的最重要的特征向量来提供速度和收敛性的改进。目的是将蒸馏应用于重-轻夸克衰变，以便在模拟中更早地获得信号，在信号丢失到噪声之前（如目前所发生的）。
