分数量子力学

Fractional Quantum Mechanics

Nick Laskin

摘要:

量子物理学的路径积分方法已经发展起来。定义了Lévy飞行路径上的分数阶路径积分。如果布朗轨道的分形性导致标准的量子力学和统计力学,那么Lévy路径的分形性导致分数量子力学和分数统计力学。通过我们的分数路径积分方法,发展了分数量子和统计力学。找到了薛定谔方程的分数阶推广,建立了非相对论量子力学粒子的能量和动量之间的关系。得到了分数阶平面波函数的方程。我们利用Fox的H函数导出了一个自由粒子量子力学核。建立了海森堡测不准关系的分数阶推广。分数阶统计力学是通过路径积分方法发展起来的。本文给出了密度矩阵运动方程的分数阶推广,自由粒子的密度矩阵可用Fox H函数表示。我们还讨论了分数和著名的费曼路径积分方法量子和统计力学之间的关系。

英文摘要:

A path integral approach to quantum physics has been developed. Fractional path integrals over the paths of the Lévy flights are defined. It is shown that if the fractality of the Brownian trajectories leads to standard quantum and statistical mechanics, then the fractality of the Lévy paths leads to fractional quantum mechanics and fractional statistical mechanics. The fractional quantum and statistical mechanics have been developed via our fractional path integral approach. A fractional generalization of the Schrödinger equation has been found. A relationship between the energy and the momentum of the nonrelativistic quantum-mechanical particle has been established. The equation for the fractional plane wave function has been obtained. We have derived a free particle quantum-mechanical kernel using Fox's H function. A fractional generalization of the Heisenberg uncertainty relation has been established. Fractional statistical mechanics has been developed via the path integral approach. A fractional generalization of the motion equation for the density matrix has been found. The density matrix of a free particle has been expressed in terms of the Fox's H function. We also discuss the relationships between fractional and the well-known Feynman path integral approaches to quantum and statistical mechanics.
