One prominent example are zero-energy Majorana fermions that were originally introduced as pure real solutions of the Dirac equation. Nowadays, they are not only discussed in the context of high energy and condensed matter physics, but it is also believed that they serve, due to their anyonic statistics, as building blocks for topological quantum computing devices. While most of the proposals for realizing and detecting Majorana fermions have been related to solid state systems, I will discuss possibilities to explore Majorana physics in cold atom systems. We will discuss possibilities to create and detect Majorana fermions in the Kitaev quantum wire and probe their anyonic nature via braiding. Further, I will explain a complementary approach to realize Majorana fermions in a cold atom setup with a fixed particle number via a specially engineered interaction. This approach is of fundamental interest for understanding the emergence of topological order.
