We study the separation of matter and antimatter driven by the growth of the Weibel instability in a matter-antimatter plasma. The plasma under consideration comprises protons and antiprotons initially at rest, along with a relativistic stream of leptons (electrons and positrons). This stream is maintained by an external force, potentially originating from phenomena such as a photon wind. Our findings reveal the rapid onset of a Weibel-type instability, leading to a distinct separation of matter and antimatter. Results from our particle-in-cell simulations are compared with an analytical model based on the linearized magnetohydrodynamics equations.
