In a general, multimode scattering setup, we show how the permutation symmetry of a many-particle input state determines those scattering unitaries that exhibit strictly suppressed many-particle transition events. We formulate purely algebraic suppression laws that identify these events and show that the many-particle interference at their origin is robust under weak disorder and imperfect indistinguishability of the interfering particles. Finally, we demonstrate that all suppression laws so far described in the literature are embedded in the general framework that we here introduce.
在一般的多模散射设置中，我们展示了多粒子输入态的排列对称性如何决定那些表现出严格抑制多粒子跃迁事件的散射幺正。我们提出了纯粹的代数抑制定律来识别这些事件，并表明它们起源处的多粒子干涉在弱无序和干扰粒子的不完全可分辨性下是稳健的。最后，我们证明了迄今为止文献中描述的所有抑制定律都嵌入在我们在这里引入的一般框架中。
