量子多极噪声与广义量子随机方程
Quantum Multipole Noise and Generalized Quantum Stochastic Equations
摘要：
量子多极（特别是偶极）噪声的概念。量子偶极噪声是量子白噪声的一种类似物，但它作用在具有不定度规的Fock空间中。量子{ \it白}噪声描述了量子动力学的随机极限近似中的前导项，而量子{ \it多极}噪声描述了对前导项的校正。我们得到并研究了包含量子偶极噪声的描述随机极限修正的广义量子随机方程。
英文摘要：
A notion of quantum multipole (in particular, dipole) noise is considered. Quantum dipole noise is an analogue of quantum white noise but it acts in a Fock space with indefinite metric. Quantum {\it white} noise describes the leading term in the stochastic limit approximation to quantum dynamics while quantum {\it multipole} noise describes the corrections to the leading term. We obtain and study the generalized quantum stochastic equations describing corrections to the stochastic limit which include quantum dipole noise.
