Inference of interference – from single to many particles

Interference and its relation to the coherence properties of the system under study can be considered well understood, at least on the level of single particle interference. This is less true when many identical particles get involved, since their – at least partial – indistinguishability gives rise to additional – many-body – interference contributions. (De-) Coherence of the many-body dynamics then hinges on the available many-body which-way information, and garnishes the many-body counting statistics. The talk will convey some of the essential structures underlying many-body interferences, and touch upon strategies to discriminate bona fide many-body interference contributions, in the absence as well as in the presence of many-body interactions.
