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.
