论文摘要
从二维中的共形界面散射是普遍的，因为反射和传输能量的通量不取决于初始状态的细节。在这封信中，我们介绍了具有薄式全息双重双重界面的能量反射和传输系数的重力计算。我们对反射系数的结果单调取决于锚定在界面上的双弦的张力，并遵守最近从ANEC衍生的，在共形场理论中衍生出的下限。在中心电荷的无限比例中回收了B（Oundary）CFT极限。
Scattering from conformal interfaces in two dimensions is universal in that the flux of reflected and transmitted energy does not depend on the details of the initial state. In this letter, we present the first gravitational calculation of energy reflection and transmission coefficients for interfaces with thin-brane holographic duals. Our result for the reflection coefficient depends monotonically on the tension of the dual string anchored at the interface, and obeys the lower bound recently derived from the ANEC in conformal field theory. The B(oundary)CFT limit is recovered for infinite ratio of the central charges.
