<p>In this paper, we investigate the streaming effect of electron–positron flows on Karpman-Washimi ponderomotive magnetization and cyclotron-radiated power in quantum pair plasmas. This study explores how does this streaming effect contribute to magnetic field amplification, and on non-stationary quantum plasmas employing the concept of Doppler shifting. According to our model, the computed magnetization and radiated power are functions of the streaming velocity of both the plasma species, Fermi velocity, wave number and wave frequency. Results indicate that the Karpman-Washimi magnetization and radiated power increase with increasing wave number, while resonance effects lead to strong enhancement near critical wave numbers. Additionally, quantum mechanical effects are found to suppress the streaming velocity impacts, and the magnetization increases with the wave number while exhibiting an inverse relationship with increasing wave frequency.</p>
