We allow that the electric potential may take distinct constant states at both far fields. The rarefaction wave is constructed by the quasineutral Euler equations through the zero-order fluid dynamic approximation, and the wave strength is not necessarily small. We prove that the local Maxwellian with macroscopic quantities determined by the quasineutral rarefaction wave is time-asymptotically stable under small perturbations for the corresponding Cauchy problem. The main analytical tool is the combination of techniques we developed in [R.-J. Duan and S.-Q. Liu, J. Differential Equations, 258 (2015), pp. 2495-2530] for the viscous compressible fluid with the self-consistent electric field and the refined energy method based on the macro-micro decomposition of the Boltzmann equation around a local Maxwellian. Both the time decay property of the rarefaction waves and the structure of the system play a key role in the proof.", keywords = "Energy method, Nonlinear stability, Quasineutral rarefaction waves, Vlasov-Poisson-Boltzmann system", author = "Renjun Duan and Shuangqian Liu", note = "Publication details (e.g. title, author(s), publication statuses and dates) are captured on an “AS IS” and “AS AVAILABLE” basis at the time of record harvesting from the data source.
