摘要:

在一个一般的,多模散射设置,我们展示了如何排列对称的多粒子输入状态确定那些散射幺正表现出严格抑制多粒子跃迁事件。我们制定纯粹的代数抑制法,确定这些事件,并表明,在其起源的多粒子干扰弱无序和不完善的不可分割性的干扰粒子下是强大的。最后,我们证明了所有的抑制法,到目前为止,在文献中描述的嵌入在一般框架,我们在这里介绍。

英文摘要:

In a general, multi-mode scattering setup, we show how the permutation symmetry of a many-particle input state determines those scattering unitaries which 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.
