一维手征通道中无质量粒子的散射
Scattering of massless particles in one-dimensional chiral channel
摘要：
我们提出了一个一般的形式描述的传播任意多粒子波包在一维多模手征通道耦合到一个系综的发射器分布在任意位置。该形式主义是基于一个直接的和精确的多粒子散射矩阵的图解系列的remmation。它是补充贝特Anglands和基于运动方程的方法，它揭示了一个简单而透明的散射态结构。特别是，我们演示了这种形式主义如何在各种例子中工作，包括散射的一个和两个光子的状态关闭两个和三个级别的发射器，关闭一个阵列的发射器以及相干光的散射。我们认为，这种形式主义可以建设性地用于研究散射的任意初始光子态的发射器与任意程度的复杂性。
英文摘要：
We present a general formalism describing a propagation of an arbitrary multiparticle wave packet in a one-dimensional multimode chiral channel coupled to an ensemble of emitters which are distributed at arbitrary positions. The formalism is based on a direct and exact resummation of diagrammatic series for the multiparticle scattering matrix. It is complimentary to the Bethe Ansatz and to approaches based on equations of motion, and it reveals a simple and transparent structure of scattering states. In particular, we demonstrate how this formalism works on various examples, including scattering of one- and two-photon states off two- and three-level emitters, off an array of emitters as well as scattering of coherent light. We argue that this formalism can be constructively used for study of scattering of an arbitrary initial photonic state off emitters with arbitrary degree of complexity.
