Yes, I attempted to do some finite size DMRG simulations, which lead to a huge memory cost due to the large system size. Thank you so much for the hint. I will let you know when I figure out how to do this.

Somehow I could not find a way to save part of MPO to disk in order to save memory in DMRG. And I really need to do so when doing some large size finite DMRG calculations. Any hints or suggestions would be really appreciated! (Actually, I am not sure if this is already done by default somewhere, if ...
