ALF项目2.4版本提供了一种用于模拟晶格费米子的通用辅助场量子蒙特卡洛算法,包含多种预定义模型和随机最大熵方法实现。

摘要:

ALF(用于晶格费米子的算法)包提供了一个通用代码,用于有限温度和投影辅助场量子蒙特卡洛算法。该代码被设计成能够模拟任何可以用单体算符之和、单体算符平方以及与具有给定动力学的玻色场耦合的单体算符所表示的模型。该包包括五个预定义的模型类别:SU(N) Kondo、SU(N) Hubbard、SU(N) t-V以及具有长程库仑排斥作用的SU(N)模型,在蜂窝、正方形和N腿晶格上,以及Z₂无约束晶格规范理论与费米子和Z₂物质耦合。还提供了一个随机最大熵方法的实现。可以从此处下载代码:https://git.physik.uni-wuerzburg.de/ALF/ALF/-/tree/ALF-2.4 并登录以提交问题。

英文摘要:

The Algorithms for Lattice Fermions package provides a general code for the finite-temperature and projective 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 a bosonic field with given dynamics. The package includes five pre-defined model classes: SU(N) Kondo, SU(N) Hubbard, SU(N) t-V and SU(N) models with long range Coulomb repulsion on honeycomb, square and N-leg lattices, as well as $Z_2$ unconstrained lattice gauge theories coupled to fermionic and $Z_2$ matter. An implementation of the stochastic Maximum Entropy method is also provided. One can download the code from our Git instance at https://git.physik.uni-wuerzburg.de/ALF/ALF/-/tree/ALF-2.4 and sign in to file issues.
