我们研究二维SQED被视为世界体积理论的D弦的存在下，D5膜与非零背景场，诱导膜之间的吸引力。在各种近似下，低能动力学由超凯勒模型（hyper-Kähler）或有挠的超凯勒模型（hyper-Kähler with torsion）给出。我们证明了在不同的D5-膜之间的弦插值对应的扭结解的存在性。D弦与基本弦的束缚态被识别为Q扭结，Q扭结又被识别为D5膜世界体积上的双音瞬子弦。
We study two-dimensional SQED viewed as the world-volume theory of a D-string in the presence of D5-branes with non-zero background fields that induce attractive forces between the branes. In various approximations, the low-energy dynamics is given by a hyper-Kähler, or hyper-Kähler with torsion, massive sigma-model. We demonstrate the existence of kink solutions corresponding to the string interpolating between different D5-branes. Bound states of the D-string with fundamental strings are identified with Q-kinks which, in turn, are identified with dyonic instanton strings on the D5-brane world-volume.
