| Details: | Non-equilibrium dynamics of many-body quantum systems reveal interesting scenarios and have been the topic of intense research in recent years. However, such problems are often found to be challenging to address both theoretically and experimentally. In this context, the dynamics of few interacting particles or the quantum walk provides a bottom-up approach to understand many-particle dynamics and at the same time reveal novel phenomena which are completely different from their many-body counterparts. In this talk, we will discuss some of the interesting phenomena that emerge from the quantum walk of interacting particles on one dimensional lattices. In the first part of the talk, we will show the formation of a non-trivial doublon or repulsively bound pairs in systems of interacting bosons as well as fermions. In the second part we will discuss the anomalous dynamics of a doublon in one dimension due to destructive interference between different paths in the quantum walk. |
