Modified vacuum polarization in the presence of a plasma
Sebastian Lundström, Philip Semrén, Haidar Al-Naseri +1
We study vacuum polarization due to strong fields, in the presence of an electron-positron plasma. For this purpose, we expand quantum kinetic equations using weak fields and slow…
Anisotropic momentum distributions due to radiation recoil in relativistic plasmas with electric and magnetic fields
Haidar Al-Naseri
The interaction of strong electromagnetic fields with plasma generates radiation accompanied by a recoil force, which can significantly alter the plasma dynamics. In this work, we…
Simulating Unruh Radiation in High-Intensity Laser-Electron Interactions for Near-Term Experimental Tests
Rafi Hessami, Haidar Al-Naseri, Monika Yadav +3
The Unruh effect predicts that a uniformly accelerating observer perceives the vacuum as a thermal bath, yet direct observation remains elusive [1]. We simulate Unruh radiation in…
Probing the transition from classical to quantum radiation reaction in relativistic plasma
Haidar Al-Naseri, Gert Brodin
We study the transition from classical radiation reaction, described by the Landau-Lifshitz model, to the quantum mechanical regime. The plasma is subject to a circularly polarized…
Electron-positron pair annihilation in kinetic plasma
Haidar Al-Naseri
The process of electron positron pair annihilation, driven by strong fields (Inverse Schwinger mechanism) and high-frequency waves, is studied using the Dirac Heisenberg Wigner for…
Applicability of semi-classical theories in the strong field plasma regime
Haidar Al-Naseri, Gert Brodin
For many purposes, classical plasma dynamics models can work surprisingly well even for strong electromagnetic fields, approaching the Schwinger critical fields, and high frequenci…
