In the first part of the seminar, I will introduce the concept of quantum simulation, following Feynmann's original vision, and discuss its applications in the field of ultracold atoms in optical lattices. Until few years ago, these applications had focused exclusively on models of relevance to condensed matter physics. I will present the key motivations that sparked a strong interest in quantum approaches to particle physics problems, in particular, in the context of (lattice) gauge theories. In the second part, I will discuss few examples on how trapped ions and cold atom gases can be used to emulate the real time dynamics of Abelian lattice gauge theories, and show how some of these approaches can be extended to certain non Abelian groups (U(N<11), SU(N<4)) utilizing alkaline-earth-like atoms. The first concrete experimental realizations in the context of the Schwinger mechanism will also be presented.
