The ALPS Project: Open Sourse Software for Classical and Quantum Lattice Models

We present the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application programs for the simulations of strongly correlated quantum lattice models, such as quantum magnets, lattice bosons or strongly correlated fermion systems. Development is done on common XML and binary data formats for, on libraries simplifying and speeding up code development and on full featured simulation programs. These programs enable non-experts to get started with numerical simulations by providing basic programs implementing the important algorithms for quantum lattice models: classical and quantum Monte Carlo (QMC) programs using non-local updates, extended ensemble simulations, exact and full diagonalization (ED) programs as well as density matrix renormalization (DMRG) programs. The software is available from our web sever at http://alps.comp-phys.org .
