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...)
1) Is it possible to do that just from a parameter file, without using the
Python interface? In particular, how is it possibile to measure the
helicity modulus?
2) Is there any place where I could find a relevant parameter file, or one
I could adapt to fit my needs?
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
