Effects of Quantum Fluctuation in Dynamical Processes (Physics)

研究了量子涨落对非线性动力学过程的影响。其中包括受驱动自旋系统的分形离解边界的量子表现、氢在三能级原子中的局域态和共振荧光。利用半经典和量子力学、Husimi表象和广义Husimi表象，通过改变涨落参数，研究了量子力学和经典力学之间的关系。最后，利用相空间中的Cantor集研究了经典和“量子分形”边界和寿命分布背后的机制。

The effects of quantum fluctuations on nonlinear dynamical processes are studied. These include the quantum manifestation of the fractal dissociation boundary of a driven spin system, the localized states of hydrogen and resonance fluorescence in a three-level atom. The relationship between quantum and classical mechanics is investigated using semiclassical and quantum mechanics, the Husimi and generalized Husimi representation and by varying a fluctuation parameter. Finally, the mechanism underlying the classical and "quantum fractal" boundary and lifetime distributions in studied using Cantor sets in phase space.
