Fig2:
vec...gif => raw density plot for time iteration files at maximum iteration time
pvec...gif => raw density plot for time iteration files without 20% centerbox
cpvec...gif => cropped/zoomed version of the latter of size 200x200 at position (307,307)

crop.sh = script to obtain cropped versions (requires Linux and graphic 
utility "convert" of ImageMagick-package).
for the cropping the pvec*gif files have been used

parameters in file name:
(cp)vec_iter_<t>_<N>_<U>_<U_R>_<w>_<\lambda>.gif

with 
t=iteration time, N=system size, U=interaction strength, 
U_R=interaction range, w = decay parameter for interaction, 
\lambda=lambda parameter of Harper model

For the case U_R=1 the decay parameter is absent in the file name

-----------------------------------------------
FIG3:
diff*gif => density plot of time dependence of one-particle density

parameters in file name:
diffus_dens_<delta_t>_(rest as in pvec files)

with delta_t=time step for one pixel in vertical direction
