We construct the tensionless limit of bosonic string theory in terms of a family of worldsheets with increasing acceleration and show that the null string emerges in the limit of infinite acceleration when the Rindler horizon is hit. We discover a novel phenomenon we call null string complementarity, which gives two distinct observer-dependent pictures of the emergence of open string physics from closed strings in the tensionless limit. The closed string vacuum as observed by the inertial worldsheet turns into a $D$ instanton in the tensionless limit, while in the complementary picture from the accelerated worldsheet, one sees the emergence of a D-25 brane. We finally discuss approaching the Rindler horizon through time evolution at constant acceleration and also show how an open string picture arises very naturally.

弦世界表上的林德勒物理学

我们用一系列加速度不断增加的世界表构造了玻弦弦理论的无张力极限，并证明了当碰到林德勒视界时，零弦出现在无限加速度的极限中。我们发现了一种被称为零弦互补的新现象，该现象为无张力极限中的闭合弦产生了两张与观察者有关的清晰图像，它们取决于开放弦物理的出现。惯性世界观察到的闭合弦真空变为$d$在无张力极限中的瞬间，而在加速的世界地图上的补充图片中，人们看到了D-25起重机的出现。最后，我们讨论了在恒定加速度下通过时间演化来接近Rindler地域的过程，并展示了打开的弦乐图片是如何非常自然地出现的。
