Hammer is a set of numerical tools for treating systems of strongly interacting quantum many body systems and is aimed primarily at the study of Fractional Quantum Hall (FQH) systems. These codes were developed within the group of Joost Slingerland which is based in the department of mathematical physics at Maynooth University, Ireland. It consists of multiple loosely coupled components as well as many associated utilities. The main components are:

Hammer is a tool for numerical calculations of FQH systems on the sphere and torus. It consists of a number of components which perform diagonalisation, wave-function evaluation, calculation of entranglement spectra, correlation functions and the Hall viscosity.


The following publications made use of Hammer.


The source code is freely available and is open source. We only ask that you acknowledge us if you use it in your work. The diagonalisation code as well as the torus wave-function construction code is at https://bitbucket.org/nmoran/hammer. While the code for constructing wave-functions on the sphere is located at https://bitbucket.org/jfulse/fqhe_mc_sphere.


Documentation on how to build and use the code is available at http://www.thphys.nuim.ie/hammer/docs/ for the diagonalisation component of the code and at https://bitbucket.org/jfulse/fqhe_mc_sphere for the sphere code.
