采用两级抽样的变分蒙特卡罗方法提高效率

Improved efficiency with variational Monte Carlo using two level sampling

Mark Dewing

摘要:

变分蒙特卡罗(VMC)采用两级抽样方法,分别对波函数的一个和两个体部分进行抽样。对自由空间中的单个Li_2分子和周期盒中的32个H_2分子进行了计算。这个简单的修改将VMC仿真的效率提高了72%。

英文摘要:

A two level sampling method is applied to variational Monte Carlo (VMC) that samples the one and two body parts of the wave function separately. The method is demonstrated on a single Li_2 molecule in free space and 32 H_2 molecules in a periodic box. This simple modification increases the efficiency of a VMC simulation by up to 72%.
