论文摘要
我们通过在所有二元和三个过程中使用QED碰撞积分来求解相对论的Uehling-uhlenbeck方程来研究Pauli阻断对相对论等离子体的热化过程的影响。为此，我们认为血浆的非平衡初始状态是强烈退化的。我们发现，当电子旋律歼灭是活跃的时，初始血浆退化很快就会破坏。结果，范围从非依赖主义到轻度相对论$ 0.1 m_e c^2 \ leq k_b t \ leq 10 m_e c^2 $温度不受Pauli Blocking的影响。相反，当电子 - 脉络体歼灭过程不活跃时，这种退化血浆中的热化过程受Pauli阻断的强烈影响。这是在非递归等离子体中的，平衡温度$ k_b t \ leq 0.3 m_e c^2 $，或者在光子电子等离子体中。在这些情况下，所有反应速率都被保利的阻塞强烈抑制，直到电子能够将能量态填充费米能量以上的能量态才能进行热化。发生这种情况后不久，在类似雪崩的过程中突然进行了热化。
We investigate the effects of Pauli blocking on thermalization process of relativistic plasma by solving relativistic Uehling-Uhlenbeck equations with QED collision integral for all binary and triple processes. With this purpose we consider nonequilibrium initial state of plasma to be strongly degenerate. We found that when electron-positron annihilation is active, initial plasma degeneracy is quickly destroyed. As a result in a wide range of final temperatures ranging from nonrelativistic to mildly relativistic $0.1 m_e c^2 \leq k_B T\leq 10 m_e c^2$ thermalization is not affected by Pauli blocking. Conversely, when electron-positron annihilation process is inactive, thermalization process in such degenerate plasma is strongly affected by Pauli blocking. This is possible either in a nonrelativistic plasma, with equilibrium temperature $k_B T\leq 0.3 m_e c^2$, or in photon-electron plasma. In these cases all reaction rates are strongly suppressed by Pauli blocking and thermalization does not occur until electrons can populate energy states above the Fermi energy. Soon after this happens thermalization proceeds suddenly in an avalanche-like process.
