运动扩散粒子的量子力学探测器模型研究

Investigation of a quantum mechanical detector model for moving, spread-out particles

Gerhard C. Hegerfeldt, Jens Timo Neumann, Lawrence S. Schulman

摘要:

我们研究了一个用于检测运动粒子的完全量子力学自旋模型。这个模型,在早期的工作中开发的,是基于一个集合的自旋在固定的位置,并在一个亚稳态,与粒子局部增强耦合的自旋的玻色子的环境。来自特定自旋的玻色子的出现表明粒子在自旋位置的存在,第一个玻色子表明它的到来。原始模型使用离散玻色子模式。在这里,我们处理的连续极限,假设的马尔可夫性质,并计算粒子到达特定区域的到达时间分布。

英文摘要:

We investigate a fully quantum mechanical spin model for the detection of a moving particle. This model, developed in earlier work, is based on a collection of spins at fixed locations and in a metastable state, with the particle locally enhancing the coupling of the spins to an environment of bosons. Appearance of bosons from particular spins signals the presence of the particle at the spin location, and the first boson indicates its arrival. The original model used discrete boson modes. Here we treat the continuum limit, under the assumption of the Markov property, and calculate the arrival-time distribution for a particle to reach a specific region.
