量子光学问题的传递形式

Transfer formalism for quantum optics problems

V. N. Gorbachev, A. I. Zhiliba

摘要:

基于Heisenberg和Schrodinger图像中Wannirer函数的定域基,给出了描述电磁场在三维介质中传播的一致量子形式。在薛定谔图象中,给出了Glauber-Sudarshan准概率的Fokker-Planck方程和相应的Langevin方程。因此,时空描述可以通过简单地改变场的时间主方程中的变量来获得。使用这种形式主义,它表明,存在的运动积分的光在介质中的传播条件下的非简并参数和双光子相互作用的结果放大模式时,光的非经典性质是保守的。考虑了光在线性介质中的量子传播,并求出了它的解。

英文摘要:

Consistent quantum formalism based on the localized basis of the Wannirer functions in Heisenberg and Schrodinger pictures to describe propagation of electromagnetic field in a three dimensional media including diffraction is presented. In the Schrodinger picture the Fokker-Planck equation for the Glauber-Sudarshan quasiprobability and corresponding Langevin equations are given. As result the space-time description is obtained by a simple changing variables in the temporal master equation of the field. Using this formalism it is shown that the existence of integrals of motion in the propagation of light in a medium under the condition of nondegenerated parametric and two-photon interactions results in amplification of modes when nonclassical properties of the light are conserved. Quantum propagation of light in a linear medium taking into account the diffraction is considered and its solution is found.
