混沌场论--一个草图

Chaotic Field Theory - a Sketch

Predrag Cvitanovic

摘要:

经典场的时空混沌动力学可以用其不稳定的时空周期解的无穷级数来描述。周期轨道理论给出了混沌动力学的全局平均值,以及对量子理论的初始半经典近似。计算修正的半经典近似的新方法的开发,特别是,非线性场变换产生的微扰修正的形式比费曼图展开更紧凑。

英文摘要:

Spatio-temporally chaotic dynamics of a classical field can be described by means of an infinite hierarchy of its unstable spatio-temporally periodic solutions. The periodic orbit theory yields the global averages characterizing the chaotic dynamics, as well as the starting semiclassical approximation to the quantum theory. New methods for computing corrections to the semiclassical approximation are developed; in particular, a nonlinear field transformation yields the perturbative corrections in a form more compact than the Feynman diagram expansions.
