The squeezing property of the light in the system of two-mode squeezing vacuum field interacting with two coupling atoms in Kerr medium is studied by means of quantum theory. The influences of coupling constant x are discussed. 研究了存在克尔介质时,双模压缩真空场与耦合二能级原子相互作用系统中光场的压缩性质,讨论了克尔介质与光场的耦合强度对光场压缩特性的影响。
It is proved from the Kerr black hole that k can only be a constant with respect to vand θ in the generalized tortoise coordinate transformation. 本文从轴对称动态Kerr黑洞的角度证明了广义、乌龟坐标变换中k只能取关于v、θ是常数的形式。
