ALPS（Algorithms and Libraries for Physics Simulations）项目是一个国际开源软件项目，旨在开发用于模拟强相关量子晶格模型（如量子磁体，晶格玻色子和强相关费米子系统）的库和应用程序。开发集中在通用的XML和二进制数据格式、简化和加速代码开发的库以及功能齐全的模拟程序上。该计划使非专家开始进行数值模拟，通过提供量子晶格模型的重要算法的基本实现：经典和量子蒙特卡罗（QMC）使用非本地更新，扩展系综模拟，精确和全对角化（艾德），以及密度矩阵重整化群（DMRG）。新版本中的变化包括用于交互模型的DMRG程序、对角化程序中对平移对称性的支持、定义自定义测量运算符的能力以及对非均匀系统（例如具有陷阱的晶格模型）的支持。该软件可从我们的网络服务器http://alps.comp-phys.org/获得。(c)2006 Elsevier B.V.保留所有权利。
We present release 1.3 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open-source software project to develop libraries and application programs for the simulation of strongly correlated quantum lattice models such as quantum magnets, lattice bosons, and strongly correlated fermion systems. Development is centered on common XML and binary data formats, on libraries to simplify and speed up code development, and on full-featured simulation programs. The programs enable non-experts to start carrying out numerical simulations by providing basic implementations of the important algorithms for quantum lattice models: classical and quantum Monte Carlo (QMC) using non-local updates, extended ensemble simulations, exact and full diagonalization (ED), as well as the density matrix renormalization group (DMRG). Changes in the new release include a DMRG program for interacting models, support for translation symmetries in the diagonalization programs, the ability to define custom measurement operators, and support for inhomogeneous systems, such as lattice models with traps. The software is available from our web server at http://alps.comp-phys.org/. (c) 2006 Elsevier B.V. All rights reserved.
