Abstract

The analysis of the possibility of correlating the momenta and coordinates of a quantum oscillator using the Robertson–Schrödinger generalization formalism and the probabilistic concept of quantum mechanics has been continued. A detailed numerical study of the quantum oscillator excitation modes under a classical impact with variable frequency is performed. An analysis of the harmonic dependence of the quantum oscillator energy showed that the oscillator has frequency intervals of parametric instability, in which the oscillation amplitudes grow exponentially. The mean energy also increases, undergoing small oscillations, which are barely noticeable in resonance, and the correlation coefficient oscillates near zero level. The probabilities of leaving the ground state and passing to the second excited state are calculated for the oscillator. The penetrability of quantum tunnel barriers of moderate depth is estimated. It is shown that the increase in the barrier penetrability upon parametric excitation at the resonant frequency may be two to three orders of magnitude higher than at a detuned frequency. The mechanisms of the radical reactions leading to the formation of reactive oxygen species in an aqueous solution under a classical impact are developed. The use of measurable probabilistic representations for describing the states of quantum particles is substantiated.

量子对化学自由基反应的影响
继续用Robertson-Schrödinger推广形式和量子力学的概率概念分析量子振荡器的动量和坐标关联的可能性。对经典频率冲击下量子振荡器的激励模式进行了详细的数值研究。对量子振子能量的谐波依赖性分析表明,振子具有参数不稳定的频率区间,振荡幅度呈指数增长。平均能量也增加,经历小的振荡,在共振中几乎不明显,相关系数在零水平附近振荡。计算了振荡器离开基态并进入第二激发态的概率。估计了中等深度量子隧道势垒的可穿透性。结果表明,在谐振频率下,参数激励下势垒穿透率的增加可能比失谐频率下高两到三个数量级。研究了在经典冲击作用下自由基反应导致水溶液中活性氧形成的机理。使用可测量的概率表示来描述量子粒子的状态得到了证实。
