高斯相空间表示的量子多体模拟

Quantum many-body simulations using Gaussian phase-space representations

P. D. Drummond, P. Deuar, J. F. Corney

摘要:

相空间表示作为从第一性原理出发研究指数复杂量子多体系统的一种可行和成功的手段,其重要性日益增加。本文回顾了这些方法的背景,从维格纳,格劳伯和Sudarshan的早期工作。我们专注于使用非经典相空间表示的现代相空间方法。这些导致了高斯表示,它统一了玻色子和费米子相空间。处理的例子包括光纤中的量子孤子,碰撞玻色-爱因斯坦凝聚体,和晶格上的强关联费米子。

英文摘要:

Phase-space representations are of increasing importance as a viable and successful means to study exponentially complex quantum many-body systems from first principles. This review traces the background of these methods, starting from the early work of Wigner, Glauber and Sudarshan. We focus on modern phase-space approaches using non-classical phase-space representations. These lead to the Gaussian representation, which unifies bosonic and fermionic phase-space. Examples treated include quantum solitons in optical fibers, colliding Bose-Einstein condensates, and strongly correlated fermions on lattices.
