摘要
Based on the scaling idea of local slopes by López et al.[Phys.Rev.Lett.94 (2005) 166103],we investigateanomalous dynamic scaling of (d+1)-dimensional surface growth equations with spatially and temporally correlatednoise.The growth equations studied include the Kardar-Parisi-Zhang (KPZ),Sun-Guo Grant (SGG),and Lai-DasSarma-Villain (LDV) equations.The anomalous scaling exponents in both the weak- and strong-coupling regions areobtained,respectively.
Based on the scaling idea of local slopes by Lopez et al. [Phys. Rev. Lett. 94 （2005） 166103], we investigate anomalous dynamic scaling of （d ＋ 1）-dimensional surface growth equations with spatially and temporally correlated noise. The growth equations studied include the Kardar-Parisi-Zhang （KPZ）, Sun-Guo-Grant （SGG）, and Lai-Das Sarma-Villain （LDV） equations. The anomalous scaling exponents in both the weak- and strong-coupling regions are obtained, respectively.
