各向异性超导体中准粒子的动量-能量张量

Momentum-energy tensor associated to the quasiparticles in anisotropic superconductors

L. A. Peña Ardila, W. Herrera, Virgilio niño

摘要:

从各向异性超导体中的Bogoliubov de Gennes方程的拉格朗日密度,我们发现与系统的准粒子相关联的动量-能量张量。为此,我们在空间和时间上进行无穷小平移,并使用诺特定理。我们证明,除了通常的条款与电磁势中的电子-空穴动态,出现条款,涉及对势,并获得从耦合的类电子和类空穴准粒子。

英文摘要:

From a Lagrangian density for the Bogoliubov de Gennes equations in anisotropic superconductors, we find the momentum-energy tensor associated to the quasiparticles of the system. For this, we make infinitesimal translations on both space and time and we use the Noether's theorem. We prove that beyond to the usual terms associated to the electron-hole dynamic in electromagnetic potentials, appears terms that involves the pair potential and that are obtained from the coupling of the electron-like and hole-like quasiparticles.
