Abstract: Even in the absence of a precise microscopic description, classical hydrodynamics provides a powerful framework for characterizing the macroscopic behavior of conserved densities, such as energy. Understanding whether and how it emerges in the late-time dynamics of many-body quantum systems has remained an enduringly hard question. In this talk, I will describe on-going experiments on a hybrid solid-state spin platform, where the underlying disordered, dipolar quantum Hamiltonian gives rise to the emergence of unconventional spin diffusion at nanometer length scales; in particular, the combination of positional disorder and on-site random fields leads to diffusive dynamics that are Fickian yet non-Gaussian. Time permitting, I will end by describing our recent efforts to realize a quantum simulation platform based upon spin defects in 2D.
