Wave-particle interactions are a fundamental mechanism to control irreversible plasma energization and energy transport throughout the Heliosphere, and universally throughout astrophysical plasma domains. The most tractable paradigm to model the plasma response to perturbations by plasma waves is the 60 year old quasilinear diffusion theory. This paradigm predominates in our understanding, but within the last two decades there has been a sustained resurgence and emergence of fundamental new questions motivated by the discovery of highly variable, intense/energetic and structured electromagnetic plasma waves and wave-particle interaction plasma physics processes by single and multi-point missions. These interactions act and control plasma energization and energy transport from microscale (gyroradius/kinetic) through to the macroscale (system scale), and in addition crucially link these scales via complex coupled fluid/mesoscale plasma physics processes. We discuss recent advances, and highlight some open, fundamental questions for wave-particle interactions that the Plasma Observatory Mission can solve via multiscale observations.
