无限扩展方势阱中的量子有效力与Bohmian观点

Quantum effective force in an expanding infinite square-well potential and Bohmian perspective

S. V. Mousavi

摘要:

薛定谔方程求解的情况下,一个粒子被限制在一个小区域的盒子与无限的墙壁。如果阱壁移动,那么由于与边界的有效量子非定域相互作用,即使粒子不在阱壁附近,它也会受到影响。结果表明,这个力除了一个负号外,等于量子势在壁边界条件下为零的梯度的期望值。研究了这种力随时间的变化。选择的Bohmian轨迹的约束粒子也计算。

英文摘要:

The Schrödinger equation is solved for the case of a particle confined to a small region of a box with infinite walls. If walls of the well are moved, then, due to an effective quantum nonlocal interaction with the boundary, even though the particle is nowhere near the walls, it will be affected. It is shown that this force apart from a minus sign is equal to the expectation value of the gradient of the quantum potential for vanishing at the walls boundary condition. Variation of this force with time is studied. A selection of Bohmian trajectories of the confined particle is also computed.
