2+1维Kardar-Parisi-Zhang模型的局部尺度不变性

Local Scale-Invariance of the 2+1 dimensional Kardar-Parisi-Zhang model

Jeffrey Kelling, Géza Ódor, Sibylle Gemming

摘要:

通过对驱动二聚体格子气模型的广泛动力学模拟,验证了局域尺度不变性理论,描述了2+1维Kardar-Parisi-Zhang表面的生长.非常精确的测量的通用autoresponse函数,使我们能够执行非线性拟合的缩放形式,建议的局部尺度不变性(LSI)。虽然简单的LSI animals似乎不工作,LSI的对数扩展的基础上的形式提供了令人满意的描述的全(测量)时间演化的autoresponse函数。

英文摘要:

Local Scale-Invariance theory is tested by extensive dynamical simulations of the driven dimer lattice gas model, describing the surface growth of the 2+1 dimensional Kardar-Parisi-Zhang surfaces. Very precise measurements of the universal autoresponse function enabled us to perform nonlinear fitting with the scaling forms, suggested by local scale-invariance (LSI). While the simple LSI ansatz does not seem to work, forms based on logarithmic extension of LSI provide satisfactory description of the full (measured) time evolution of the autoresponse function.
