介电矩阵的几何相位

Geometric Phase From Dielectric Matrix

Dipti Banerjee

摘要:

将偏振光子看作球谐函数的二分量旋量,求出了各向异性光学介质的介电性质$(2\times2)$,并从两个方面计算了单偏振光子的几何相位。通过扭曲介质矩阵的相位二形式和Pancharatnam相位(GP)通过入射偏振光子在扩展庞加莱球上的封闭三角形路径上的角动量的变化。与手征光子的自旋角动量有关的螺旋度在发展这些相位完整性中起着关键作用。

英文摘要:

The dielectric property $(2\times2)$ of the anisotropic optical medium is found out considering the polarized photon as two component spinor of spherical harmonics.The Geometric Phase of single polarized photon has been evaluated in two ways. The phase two-form of the dielectric matrix through a twist and the Pancharatnam phase (GP) through the change of angular momentum of the incident polarized photon over a closed triangular path on the extended Poincare sphere. The helicity in connection with the spin angular momentum of the chiral photon plays the key role in developing these phase holonomies.
