简单量子系统中的量子几何张量(Fubini-Study度规):教学导论

Quantum Geometric Tensor (Fubini-Study Metric) in Simple Quantum System: A pedagogical Introduction

Ran Cheng

摘要:

几何量子力学是一种新的和有前景的方法,其动机是相信我们的世界最终是几何的。其核心是一个称为量子几何张量(或Fubini-Study度量)的量,它是一个复张量,实部作为度量“量子距离”的黎曼度量,虚部是贝里曲率。在对基本形式进行物理介绍之后,我们说明了它在绝热和非绝热系统中的物理意义。

英文摘要:

Geometric Quantum Mechanics is a novel and prospecting approach motivated by the belief that our world is ultimately geometrical. At the heart of that is a quantity called Quantum Geometric Tensor (or Fubini-Study metric), which is a complex tensor with the real part serving as the Riemannian metric that measures the `quantum distance', and the imaginary part being the Berry curvature. Following a physical introduction of the basic formalism, we illustrate its physical significance in both the adiabatic and non-adiabatic systems.
