Introduction#
The auxiliary-field quantum Monte Carlo package ALF [1, 2] is a powerful tool for simulating a broad set of fermionic systems, but since it is written in Fortran, it is not very dynamic and can be a bit daunting for new users.
Aiming to address this challenge, pyALF is a set of Python scripts built on top of ALF. It is meant to simplify the different steps of working with ALF, including:
Obtaining and compiling the ALF source code
Preparing and running simulations
Postprocessing and displaying the data obtained during the simulation
The source codes for both ALF and pyALF are publicly available at https://git.physik.uni-wuerzburg.de/ALF.
This documentation is structured in the following way:
Prerequisites and installation describes the prerequisites of pyALF and how to set things up to be able to use it in a productive manner.
Usage displays the features of pyALF and how to use them on small examples.
For a reference on pyALF’s features, see Reference.
