本文针对随机波动外磁场中带电粒子的薛定谔方程,提出一种结合确定性平均与波动行为的随机薛定谔方程,证明其与原模型极限行为一致,为研究相关可观测量分布提供了简便方法。
AI 中文摘要
我们研究在随机波动外磁场中带电粒子的薛定谔方程,建立奇异扰动极限,在此极限下解收敛到带有高斯波动的确定性薛定谔方程。我们提出一种随机薛定谔方程,其结合了确定性平均与波动的行为,证明它与原模型具有相同的极限行为,同时为研究相关可观测量的分布提供了更简便的方法。
英文摘要
We consider the Schrödinger equation for a charged particle in a randomly fluctuating external magnetic field and establish a singular perturbation limit in which the solution converges to a deterministic Schrödinger equation with Gaussian fluctuations. We propose a stochastic Schrödinger equation incorporating the behavior of both the deterministic average and the fluctuations and show that it has the same limiting behavior as the original model, while providing a simpler way to study the distribution of relevant observables.
