                         factor by the confining potential in semiconductor nanostructures 
                         is theoretically investigated. The effective g factor for 
                         electrons in structures with interacting nanolayers, or coupled 
                         quantum wells (QWs), is obtained with an analytical and yet 
                         accurate multiband envelope-function solution, based on the linear 
                         8 x 8 k . p Kane model for the bulk band structure. Both 
                         longitudinal and transverse applied magnetic fields are considered 
                         and the g-factor anisotropy (i.e., the difference between the two 
                         field configurations) is analyzed over the entire space spanned by 
                         the two structure parameters: the thickness of the active layers 
                         and the thickness of the tunneling barrier separating them. 
                         Two-dimensional anisotropy maps are constructed for symmetric and 
                         asymmetric InGaAs coupled QWs, with InP tunneling barriers, that 
                         reproduce exactly known single-layer or QW results, in different 
                         limits. The effects of the structure inversion asymmetry on the 
                         mesoscopic g-factor renormalization are also discussed, in 
                         particular the negative anisotropies for thin-layer structures. 
                         Such multilayer structures form an excellent testing ground for 
                         the theory, and the analytical solution presented, which is 
                         perfectly consistent over the whole space of parameters, leads to 
                         helpful expressions and can guide further research on the 
                         mechanisms of this mesoscopic renormalization.",
