论文摘要
在模拟未结合的量子系统时,经常会施加复杂的吸收电位。虽然通常仅仅是为了避免在数值边界处进行伪影,但我们还可以显示如何使用吸收器来探测所吸收吸收的颗粒的特征。这样,可以保留有关去除的颗粒的信息。此外,我们解释了这种吸收者在允许模拟动态模拟中模拟测量行为的意义上如何充当检测器。
Complex absorbing potentials are frequently imposed when simulating unbound quantum systems. While this is usually done solely in order to avoid artifacts at the numerical boundary, we show how absorbers may also be used to probe the characteristics of the particle undergoing absorption. This way, information about the removed particles may be retained. Moreover, we explain how -- and when -- such absorbers act as detectors in the sense that they allow for simulating the act of measurement in dynamical simulations.
