论文摘要
我们研究了有限温度下的中等质量核中的费米子Matsubara绿色功能。具有粒子振动耦合（PVC）原点的动力核的单特屈服dyson方程是根据Dirac Spinors制定和求解的，该旋转器以Dirac Spinors的基础，通过Meson-Nucleon Covariant能量密度的功能最小化了宏伟的规范势。在能量依赖性的自我能源的领先近似值中考虑了均值之外的PVC相关性，并为费米子繁殖器获得了有限温度dyson方程的完整解。在这种方法中，我们研究了单粒子状态的碎片及其随核系统温度的演变，$^{56,68} $ ni和$^{56} $ fe $ fe与核心崩溃的超新星相关。能量依赖性或动态的核子有效质量是在各种温度下从PVC自能源中提取的。
We study the fermionic Matsubara Green functions in medium-mass nuclei at finite temperature. The single-fermion Dyson equation with the dynamical kernel of the particle-vibration-coupling (PVC) origin is formulated and solved in the basis of Dirac spinors, which minimize the grand canonical potential with the meson-nucleon covariant energy density functional. The PVC correlations beyond mean field are taken into account in the leading approximation for the energy-dependent self-energy, and the full solution of the finite-temperature Dyson equation is obtained for the fermionic propagators. Within this approach, we investigate the fragmentation of the single-particle states and its evolution with temperature for the nuclear systems $^{56,68}$Ni and $^{56}$Fe relevant for the core-collapse supernova. The energy-dependent, or dynamical, nucleon effective mass is extracted from the PVC self-energy at various temperatures.
