vec...gif => raw density plot of time evolution states for the \alpha_1 case

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

with 
t=iteration time, N=system size, U=interaction strength, 
U_R=interaction range=1 (in fig 16), \lambda=lambda parameter of Harper model



fig_onep_<U>.eps => for U=2.25 and U=3.6 density plot of time evolution one-particle density at t=100,1000,10000
