Hi,
I'd need to simulate a three-dimensional XY model, studying the helicity modulus as a function of temperature. (3D XY means that the sites are defined on a cubic lattice, while the spins are constrained on a plane)
I'd have a few questions:
- Can I do that with ALPS? (I suppose the answer will be yes...)
Yes, partially.
- Is it possible to do that just from a parameter file, without using the Python interface?
Yes.
In particular, how is it possibile to measure the helicity modulus?
no, not yet but this could be added.
- Is there any place where I could find a relevant parameter file, or one I could adapt to fit my needs?
Just take an Ising model example and change the model to XY
Thanks in advance (and sorry if the question is too silly, I have been playing with ALPS for a couple of days so far! I have searched for my issues in the documentation by I could not find relevant examples!)
Best Regards, Alvise
