Q: List of commercial software for doing simulation of low-dimensional quantum spin systems or quantum magnetism

I am interested in investigating the thermodynamic properties (in particular, magnetism: statics or dynamics) of low-dimensional quantum spin systems. Methods/techniques like DMRG, QMC,ED,DMFT, etc. are used for investigating low-dimensional quantum spin systems. What are the commercial packages ...

+1 but this question needed an enormous number of grammatical and formatting fixes. Please take a look at my edits and study them so that others don't have to make so many edits next time. I've removed everything about bulk systems because otherwise this question will be "closed" by community members for being "too broad", but you can ask that question next after this question has been up for long enough. Also, why does the software need to be commercial? Why can't you use a free DMRG code? — Nike Dattani 28 mins ago

@NikeDattani, Thank you so much for your edits. Yes, I will be more careful next time. — Quantum_Magnet 11 mins ago

Thank you. I noticed that you removed the sentence about "paid" software, but left "commercial" in the title. Is there any reason why you're interested in "paid" or "commercial" software? Why is free software not suitable for your needs? — Nike Dattani 9 mins ago

@NikeDattani, I myself have written DMRG Code. Commercial packages are considered to be more extensive, so I was looking for the such possibilities. — Quantum_Magnet 5 mins ago

@NikeDattani Yes, I have removed the sentence about "paid" software, but left "commercial" in the title, Because I think it was repetition of same thing. — Quantum_Magnet 2 mins ago

Frankly speaking, I've never heard of a commercial DMRG code, and I disagree with your assumption that commercial codes are more extensive (at least I disagree in terms of quantum codes that are used for academia, such as all DMRG codes because no DMRG code is used for real-life engineering outside of academia as far as I know).

I would suggest to just look for codes in general, whether or not they're commercial, and then hopefully you'll get answers describing all codes (both commercial and non-commercial, assuming that such codes exist).

But if you're going to do that for DMRG, then the question becomes a duplicate of this one which I linked above:

Q: 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 how to write your own calculations that do nontrivial things, not just run an example code that th...

So I think bulk properties are the ones to focus on here (which you mentioned in first version of your question), so I'll change your question accordingly.

Q: What software can simulate bulk magnetism?

I am interested in investigating bulk magnetism computationally. What are the packages available for it? Any help in this direction will be appreciated. Please answer with the format of the answer in similar questions before, such as: Package for computing properties of excited vibrational state...

@Feeds ok thanks, nike for your time and suggestion.

@Feeds Yes, You have changed the question, Very nice!

@NikeDattani I was looking the codes similar to VASP, Quantum-Expresso.

@Quantum_Magnet Quantum ESPRESSO is free though.

And about commercial codes being "more extensive" than free ones, that's not clear in the case of VASP vs QE:

Q: Quantum ESPRESSO vs VASP

We know that both Quantum ESPRESSO and VASP can perform lots of different kinds of simulations of materials. But what can VASP do that Quantum ESPRESSO can not, and vice-versa?
