Type of Event (for grouping events):

The computational difficulty of solving fully quantum many-body spin problems is a significant obstacle to understanding the behavior of strongly correlated quantum matter. This talk will introduce how arrays of trapped ions can emulate the behavior of interesting quantum condensed-matter materials. First, I will review some of the groundbreaking experiments to explore the physics of interacting spin systems using 1D chains of ions. Then, I will describe our creation of a 2D trapped ion array, which significantly expands the classes of quantum matter that can be emulated. We characterize the structural phase boundaries and vibrational mode frequencies of ions in this geometry, as well as the heating rates parallel and perpendicular to the 2D crystal plane. We find that these 2D crystals will serve as a robust platform for future quantum computation and simulation experiments.
