从理论上研究了利用磁力显微镜从扩展缺陷中解压缩涡旋线的问题。我们研究了孤立涡旋与普通缺陷如柱钉和双平面的解压缩，以及在有其他涡旋存在的情况下涡旋与平面的解压缩。我们用解析和数值方法证明了在无序存在和不存在的情况下，单个涡旋解压缩跃迁的普适性质仅依赖于缺陷的维数。在二维平面上，涡的解压缩对涡的性质非常敏感。特别地，这种解压缩实验可以用来测量平面内涡旋的“Luttinger液体参数”。此外，我们还提出了一种利用实验直接测量涡流线张力的方法。

英文摘要：
The unzipping of vortex lines using magnetic-force microscopy from extended defects is studied theoretically. We study both the unzipping isolated vortex from common defects, such as columnar pins and twin-planes, and the unzipping of a vortex from a plane in the presence of other vortices. We show, using analytic and numerical methods, that the universal properties of the unzipping transition of a single vortex depend only on the dimensionality of the defect in the presence and absence of disorder. For the unzipping of a vortex from a plane populated with many vortices is shown to be very sensitive to the properties of the vortices in the two-dimensional plane. In particular such unzipping experiments can be used to measure the ``Luttinger liquid parameter'' of the vortices in the plane. In addition we suggest a method for measuring the line tension of the vortex directly using the experiments.
