Quantum walk of two composite bosons — •Pedro Weiler, Mama Kabir Njoya Mforifoum, Gabriel Dufour, and Andreas Buchleitner — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg i.Br.

Many-body interference plays a key role in the dynamics of identical particles. In this contribution we discuss the quantum walk of two identical composite bosons on a 1D lattice. We consider composites made up of either two fermions or two bosons bound by contact interactions. Depending on the quantum statistics of the composite bosons' constituents, we observe different dynamical behaviours arising from an interplay of interaction and exchange processes.
