Interference of two composite bosons — Mama Kabir Njoya Mforifoum, Andreas Buchleitner, and •Gabriel Dufour — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

We study the Hong-Ou-Mandel interference of two identical composite bosons, each formed of two bosonic or fermionic constituents, as they scatter against a potential barrier in a one-dimensional lattice. For tightly bound composites, we show that the combination of their constituents' mutual interactions and exchange symmetry gives rise to an effective interaction between the composites, which induces a reduction of the interference contrast.
