hhtop is a program to compute interaction-induced renormalizations in the Haldane-Hubbard model.
hhtop v1.0 can be used to compute:
- the renormalization of the topological phase diagram at first order.
- the wave function renormalizations at second order.

The numerical capabilities of hhtop are provided by the libinum library. Version 1.0.1 or later is required. A copy of libinum-1.0.1 is provided with the source code, and is, by default, compiled at the same time as hhtop.
