Title: Quantum simulations of many-body spin dynamics with trapped ions

Abstract: Trapped atomic ions are a powerful and versatile platform for emulating quantum spin systems. I will give a brief overview of the tools that are currently available to experiments, particularly the various spin models that can be generated by applying spin-dependent optical dipole forces to a chain of interacting ions. We have performed a variety of experiments using this toolkit, including measurements of the many-body energy spectrum [1] and of the propagation of spin correlations after a sudden quench [2], as well as demonstrated a quantum integer-spin chain [3]. This system holds promise for scaling quantum simulations up to several tens of spins, a size where many classical computations become intractable.
