The Algorithms for Lattice Fermions package provides a general code for the
finite temperature auxiliary field quantum Monte Carlo algorithm. The code is
engineered to be able to simulate any model that can be written in terms of
sums of single-body operators, of squares of single-body operators and
single-body operators coupled to an Ising field with given dynamics. We provide
predefined types that allow the user to specify the model, the Bravais lattice
as well as equal time and time displaced observables. The code supports an MPI
implementation. Examples such as the Hubbard model on the honeycomb lattice and
the Hubbard model on the square lattice coupled to a transverse Ising field are
provided and discussed in the documentation. We furthermore discuss how to use
the package to implement the Kondo lattice model and the
$SU(N)$-Hubbard-Heisenberg model. One can download the code from our Git
instance at https://alf.physik.uni-wuerzburg.de and sign in to file issues.
