摘要

我们提出了一种量子传感器的理论模型，它能以非常简单的方式确定电场强度是否具有指定值。该模型基于以下事实：当双阱量子系统在外部直流电场作用下发生共振虚部的精确交叉时，就会出现阻尼跳动现象，而如果没有这种交叉，就不会出现这种现象。然后在一个明确的一维模型上对这一结果进行了数值检验。

Resonances crossing and electric field quantum sensors*

We propose a theoretical model for a quantum sensor that can determine in a very simple way whether the intensity of an electric field has an assigned value or not. It is based on the fact that when an exact crossing of the imaginary parts of the resonances occurs in a double-well quantum system subject to an external DC electric field, a damped beating phenomenon occurs, which is absent if there is no such a crossing. This result is then tested numerically on an explicit one-dimensional model.

期刊介绍： Physica Scripta is an international journal for original research in any branch of experimental and theoretical physics. Articles will be considered in any of the following topics, and interdisciplinary topics involving physics are also welcomed: -Atomic, molecular and optical physics- Plasma physics- Condensed matter physics- Mathematical physics- Astrophysics- High energy physics- Nuclear physics- Nonlinear physics. The journal aims to increase the visibility and accessibility of research to the wider physical sciences community. Articles on topics of broad interest are encouraged and submissions in more specialist fields should endeavour to include reference to the wider context of their research in the introduction.
