The time dynamics of strongly correlated many-body systems is a notoriously challenging problem, with implications ranging from condensed matter to high-energy physics. Both numerical and analytical techniques remain scarce, limiting our understanding of how these systems evolve in time. The Eigenstate Thermalization Hypothesis (ETH) offers a powerful framework to explain how generic many-body systems thermalize under a wide variety of initial conditions. However, in recent years, many counterexamples have emerged where ETH breaks down. Systems exhibiting quantum many-body scars provide a particularly striking case, as they can prevent thermalization in special situations. In this talk, I will discuss the appearance of quantum many-body scars within a class of lattice gauge theories, combining numerical and analytical approaches. These results are not only relevant for near-term quantum simulators but may also lead us to towards a better understanding of quantum field theories.
