利用递归格林函数技术对弱磁场中反点晶格中的量子干涉效应进行了数值研究。在理想的反点晶格中，不规则的Aharonov-Bohm （AB）型振荡随反点直径和周期敏感变化。ab型振荡消失，Al'tshuler， Aranov和Spivak （AAS）振荡在反点大小或位置波动的存在下表现出来。原子吸收光谱在六边形晶格中的振荡比在方形晶格中的振荡强得多，与实验结果一致。1996美国物理学会。
A numerical study is performed on quantum interference effects in antidot lattices in a weak magnetic field with the use of a recursive Green's function technique. An irregular Aharonov-Bohm (AB)-type oscillation varying sensitively with antidot diameters and periods is dominant in ideal antidot lattices. The AB-type oscillation disappears and an Al'tshuler, Aranov, and Spivak (AAS) oscillation manifests itself in the presence of fluctuations in the size or position of antidots. The AAS oscillation is much stronger in hexagonal lattices than in square lattices, in good agreement with experiments. \textcopyright{} 1996 The American Physical Society.
