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.
hhtop is written in C, and can run on any POSIX compliant system, including GNU/Linux and OSX. hhtop is linked against the GNU MPFR, GNU GMP and libinum libraries.
hhtop is made available under an Apache 2.0 license, which allows copying, sharing and modifying the source code, among other things. Details can be found at https://www.apache.org/licenses/LICENSE-2.0.
The source code is made available here:
- Source tarball: hhtop-1.0.tar.gz
- Git repository: hhtop-git
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.
