摘要

在周期性驱动量子系统的弗洛凯理论框架下,研究证明圆极化电磁场对石墨烯的辐照会在斥力势的核心诱导出一个吸引力区域。因此,出现了被斥力势束缚的准静态电子态。本文讨论了石墨烯中的这种场诱导态与通常的电子抛物线色散系统的区别,并探讨了这些态在石墨烯的电子传输和光学光谱中可能的表现形式。

Electronic states bound by repulsive potentials in graphene irradiated by a circularly polarized electromagnetic field.

In the framework of the Floquet theory of periodically driven quantum systems, it is demonstrated that irradiation of graphene by a circularly polarized electromagnetic field induces an attractive area in the core of repulsive potentials. Consequently, the quasi-stationary electron states bound by the repulsive potentials appear. The difference between such field-induced states in graphene and usual systems with the parabolic dispersion of electrons is discussed and possible manifestations of these states in electronic transport and optical spectra of graphene are considered.

期刊介绍: Journal of Physics: Condensed Matter covers the whole of condensed matter physics including soft condensed matter and nanostructures. Papers may report experimental, theoretical and simulation studies. Note that papers must contain fundamental condensed matter science: papers reporting methods of materials preparation or properties of materials without novel condensed matter content will not be accepted.
