iDMRG: are there subtle ways that finite-size effects creep in?

I know that iDMRG (infinite-density matrix renormalization group) calculations are usually treated as capturing all the thermodynamic-limit behavior of a system, and I have also heard that there are ...

What are the types of DMRG?

The following questions have worked out very well 😊 : What are the types of Quantum Monte Carlo? What are the types of SCF? What are the types of MCSCF? What are the types of ab initio Molecular ...

How does infinite DMRG work? [duplicate]

iDMRG or infinite-size density matrix renormalization group, is a common technique in condensed matter. It seems that usually people believe that it reliably captures infinite-size behavior. I have ...

What are some DMRG packages with an easy learning curve?

I've been meaning to learn how to use DMRG (density matrix renormalization group) for a long time. Which packages have an easy learning curve? I specifically mean it should be easy to actually learn ...

Is python sufficient for serious tensor network or DMRG calculations?

There are enough tensor-network/DMRG packages that support python (ALPS, OpenMPS, pyUni10) that it would seem (to an outsider) that it's possible to do some substantial work with DMRG without messing ...

Is there any good review paper on the density matrix renormalization group (DMRG) method?

I would appreciate if someone could recommend me good review literature on the density matrix renormalization group (DMRG) method, especially for magnetic systems.
