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
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:
Diagonalisation component: Codes for performing large scale exact
diagonalisation calculations for FQH systems. Includes codes for
calculating many observables including correlations functions and
Wave-function construction: Codes for constructing a broad range of
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.
