标题： Damping Rate of Quasiparticles in Degenerate Ultrarelativistic Plasmas

摘要： 我们计算了在零温度下的密集相对论等离子体中费米子的阻尼率。 在费米海之上，阻尼率由软磁光子（或QCD中的胶子）的交换主导，并与$(E-\mu)$成正比，其中 E 是费米子能量，$\mu$是化学势。 我们还计算了软电光子和硬光子的贡献。 如同非相对论情况一样，纵向光子的贡献与$(E-\mu)^2$成正比，因此在相对论情况下不是主要贡献。 显示英文摘要

摘要： We compute the damping rate of a fermion in a dense relativistic plasma at zero temperature. Just above the Fermi sea, the damping rate is dominated by the exchange of soft magnetic photons (or gluons in QCD) and is proportional to $(E-\mu)$, where E is the fermion energy and $\mu$ the chemical potential. We also compute the contribution of soft electric photons and of hard photons. As in the nonrelativistic case, the contribution of longitudinal photons is proportional to $(E-\mu)^2$, and is thus non leading in the relativistic case.
