图解蒙特卡罗

Diagrammatic Monte Carlo

Kris Van Houcke, Evgeny Kozik, Nikolay Prokof'ev, Boris Svistunov

摘要:

图解蒙特卡罗(Diagrammatic Monte Carlo,简称DiagMC)是一种数值技术,它允许人们计算以图解展开形式指定的量,后者是多体量子统计的标准工具。符号问题,通常是致命的蒙特卡罗方法,似乎是可控的DiagMC。本文首先介绍DiagMC的基本原理,然后详细描述了用于相互作用费米子(哈伯德模型)的DiagMC方案,并给出了状态方程的第一个说明性结果。

英文摘要:

Diagrammatic Monte Carlo (DiagMC) is a numeric technique that allows one to calculate quantities specified in terms of diagrammatic expansions, the latter being a standard tool of many-body quantum statistics. The sign problem that is typically fatal to Monte Carlo approaches, appears to be manageable with DiagMC. Starting with a general introduction to the principles of DiagMC, we present a detailed description of the DiagMC scheme for interacting fermions (Hubbard model), as well as the first illustrative results for the equations of state.
