Moyal积--准厄米量子力学的新视角

Moyal products -- a new perspective on quasi-hermitian quantum mechanics

FG Scholtz, HB Geyer

摘要:

引入非厄米哈密顿和其他观测量的理由进行审查和公开的问题确定。提出了一种基于Moyal积的计算准厄米系统度规的新方法。这种方法不仅是一种有效的计算方法,而且也提出了一个新的视角,准厄米量子力学,值得进一步探索。特别是,我们提出了一些第一个结果链接的Berry连接和曲率的非微扰性能和度量。

英文摘要:

The rationale for introducing non-hermitian Hamiltonians and other observables is reviewed and open issues identified. We present a new approach based on Moyal products to compute the metric for quasi-hermitian systems. This approach is not only an efficient method of computation, but also suggests a new perspective on quasi-hermitian quantum mechanics which invites further exploration. In particular, we present some first results which link the Berry connection and curvature to non-perturbative properties and the metric.
