非零温下的全息静态横向偏振

A Holographic Static Transverse Polarization At Non-zero Temperatures

Lei Yin, Jialin Gao

摘要:

在渐近$D=3+1$维Anti-de Sitter时空中,数值研究了由Einstein-Maxwell理论全息确定的复动量平面中极化张量静态横向分量的解析结构.这种强耦合的横向极化在低温下在光轴上呈现出一对共轭的简单极化,这与相应的极化的纵向分量和弱耦合的对应极化的纵向分量不同。

英文摘要:

The analytical structure of a static transverse component of polarization tensor in complex momentum plane is numerically studied, which is holographically determined by a Einstein-Maxwell theory in asymptotically $D=3+1$ dimensional Anti-de Sitter spacetime. This strongly-coupled transverse polarization shows a pair of conjugate simple poles on the imaginary-axis at low temperature, which is different with the longitudinal component of the corresponding polarization and the counterpart in its weakly-coupled version.
