We re-examine the (inverse) Fermi accelerator problem by resorting to a quantum trajectory description of the dynamics. Quantum trajectories are generated from the time-independent Schrodinger equation solutions, using a unipolar treatment for the (light) confined particle and a bipolar treatment for the (heavy) movable wall. Analytic results are presented for the exact coupled two-dimensional problem, as well as for the adiabatic and mixed quantum-classical approximations.

时间无关（逆）费米加速器的量子轨迹描述

我们通过对动力学的量子轨迹描述重新审视（逆）费米加速器问题。量子轨迹是从与时间无关的薛定谔方程解产生的，对（轻）受限粒子使用单极处理，对（重）可移动壁使用双极处理。给出了精确耦合二维问题以及绝热和混合量子经典近似的解析结果。
