Abstract
We propose a novel Particle-in-Cell method that is intrinsically free of the Numerical Cherenkov Instability for simulations of relativistically flowing plasmas. It is conceptually independent of specific solvers or geometries and - unlike previous suppression strategies - we completely avoid artificial modifications of the electromagnetic fields. Application is shown at the example of Lorentz-boosted frame simulations of plasma accelerators, achieving excellent accuracy and highest speed-ups using our spectral, quasi-3D code FBPIC.
