论文摘要
为开源Micromagnetics Code Mumax3提供了基于晶格的方法来计算拓扑天空电荷的实现。比较了三种不同的测试用例，它相对于基于有限差衍生物的现有方法的准确性进行了比较。发现基于晶格的方法对于有限温度动力学以及扩展系统中的成核和an灭过程更为强大。
An implementation of a lattice-based approach for computing the topological skyrmion charge is provided for the open source micromagnetics code MuMax3. Its accuracy with respect to an existing method based on finite difference derivatives is compared for three different test cases. The lattice-based approach is found to be more robust for finite-temperature dynamics and for nucleation and annihilation processes in extended systems.
