Hi, ALPS users and developers

    I have two questions about calculation of entropy by using DMRG:

   (1)If I can calculate the entropy of system by DMRG and how to get final entropy data besides standard output in the screen?

   (2)What dependence of entropy on system's properties ? In other words if it is depend on gapped or gapless ,chain or quasi-1D system.

 

  I would be very grateful for your responce.
