Getting Started

ALPS is a software package for simulating correlated systems. It provides programs for Classical Monte Carlo, Quantum Monte Carlo, and Density Matrix Renormalization Group simulations.

Obtaining ALPS

The simplest way to start using ALPS is to install the prebuilt Python package:

$ pip install pyalps

For more control over the installation — or to build with HPC support — choose one of the methods below:

Quickstart Tutorials

Once ALPS is installed, try one of the quickstart examples:

• Classical Monte Carlo — 2D Ising model phase transition
• Quantum Monte Carlo — Kondo screening with the hybridization expansion solver
• Density Matrix Renormalization Group — ground state energy of a Heisenberg chain
• Exact Diagonalization — triplet gap of a spin chain
