Daisy improved corrections to the effective potential? #21

Open quarkquartet opened 4 years ago

quarkquartet commented 4 years ago

It seems that the generic_potential.py module does not include the daisy improved corrections. Are there any way to improve this? Or this package actually have this?

You should be able to include thermal mass corrections in the boson_massSq method which amounts to the same thing (I think, it's been a long while since I worked on this). See e.g. https://arxiv.org/pdf/1204.5464.pdf eqs 12-14. In general, you can change the potential function to be whatever you wish. You can completely replace Vtot(X, T) to include different corrections or exotic functional forms so long as you keep the same call signature and the resulting function is continuously differentiable.
