Abstract: Individually trapped neutral atoms are a promising platform for the controlled, bottom-up engineering of quantum many-body systems. These systems enable manipulation of large numbers of atoms and facilitate strong interactions via excitation to Rydberg states, paving the way for the realization of programmable spin models. In the first part of this talk, I will provide an overview of the quantum many-body phenomena that emerge in these systems, both in and out of equilibrium. I will then focus on global quench dynamics in Rydberg atom arrays, exploring thermalization phenomena such as quantum many-body scars. Furthermore, I will discuss the computational complexity underlying this dynamics by demonstrating its capability to encode arbitrary quantum circuits. In the second part, I will address methods to realize topologically ordered states within Rydberg atom arrays. Specifically, I will present novel approaches to detecting topological order in such quantum simulators.
