Dear alps users:
      Now I am learning ALPS. It's useful for me.
     
    But I have question:
        How to get the wave function or some calculation about it,
     for example,
    1.the participation ratio(=1 / \sum_i £ü< i | \psi > |^4 )
    2.calculation of entropy.  I search in the mail group, some people face the same        
    difficulty, but I cannot find the answer, can any of you provide me the solution?

Thank you! Best wishes to you!
