ALPS LatticeHOWTO

Definition of lattices

How to specify lattices (graphs) within the ALPS-framework?

In this HOWTO we explain how lattices and graphs are specified within the ALPS-framework. In simulations for lattice models, it is then convenient to specify the lattice used for the simulation in an input file.

We explain the following issues:

• How to specify a simple graph in terms of vertices and edges
• How to specify lattices and unit cells
• How to specify graphs corresponding to a lattice with a unit cell
• How to create a library of lattices and graphs
• How to check a graph generated from a lattice definition
