Emerging platforms to answer basic theoretical questions about correlated quantum matter — •Joel Moore — University of California, Berkeley — Lawrence Berkeley National Laboratory

New insights into correlated quantum materials have been achieved using a variety of experimental platforms and computational approaches that did not exist a few years ago. This talk begins with the example of the quantum Heisenberg chain and its unusual spin superdiffusion at high temperatures, which following initial theoretical predictions has now been observed in neutron scattering off crystals (2021), quantum emulators of ultracold atoms (2022), and gate-based superconducting quantum computers (2023-2024). One can ask more generally which problems in quantum materials are likely to be amenable to new approaches and which are likely to remain challenging at least in the near term. Using examples drawn from different materials classes, particularly spin systems and two-dimensional electronic materials, a guess at the possible sequence of progress in this area is presented.
