环境引力退相干与张量噪声模型
Environmental gravitational decoherence and a tensor noise model
摘要：
讨论了由于引力波的发射而引起的大质量系统相干性的降低。特别是，我们调查的背景下，环境引力退相干的干涉实验。的时间演化的约化密度矩阵解析求解使用路径积分形式主义。此外，我们还研究了张量噪声对大质量系统相干性的影响。我们讨论了张量噪声的一个特定的选择显示出相似的Diosi和Penrose提出的机制。
英文摘要：
We discuss decrease of coherence in a massive system due to the emission of gravitational waves. In particular we investigate environmental gravitational decoherence in the context of an interference experiment. The time-evolution of the reduced density matrix is solved analytically using the path-integral formalism. Furthermore, we study the impact of a tensor noise onto the coherence properties of massive systems. We discuss that a particular choice of tensor noise shows similarities to a mechanism proposed by Diosi and Penrose.
