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:
0) Can I do that with ALPS? (I suppose the answer will be yes...)
Yes, partially.
1) 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.
2) 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
