碰撞时间有限的量子线性Boltzmann方程
Quantum linear Boltzmann equation with finite intercollision time
摘要：
在通常的量子版本的经典线性玻尔兹曼方程构造的气体中的量子化的测试粒子指出的instruments。这些都与动量退相干的不正确的形式处理有关。我们证明了理想碰撞将导致完全的动量退相干，相干的持续性仅仅是由于有限的碰撞时间。提出了一个新的量子线性玻尔兹曼方程。
英文摘要：
Inconsistencies are pointed out in the usual quantum versions of the classical linear Boltzmann equation constructed for a quantized test particle in a gas. These are related to the incorrect formal treatment of momentum decoherence. We prove that ideal collisions would result in complete momentum decoherence, the persistence of coherence is only due to the finite intercollision time. A corresponding novel quantum linear Boltzmann equation is proposed.
