留下“脚印”但没有“指纹”的散射器
Scatterer that leaves "footprints" but no "fingerprints"
摘要：
我们计算了在量子线的截止频率处存在单点缺陷的量子线的精确传输系数。我们表明，虽然电导模式（即，散射）受到缺陷存在的强烈影响，图案完全独立于缺陷的特性（即，导致散射的缺陷不能从该图案中识别）。
英文摘要：
We calculate the exact transmission coefficient of a quantum wire in the presence of a single point defect at the wire's cut-off frequencies. We show that while the conductance pattern (i.e., the scattering) is strongly affected by the presence of the defect, the pattern is totally independent of the defect's characteristics (i.e., the defect that caused the scattering cannot be identified from that pattern).
