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

摘要： 在周期驱动量子系统的Floquet理论框架内，证明了用圆偏振电磁场照射石墨烯会在排斥势的核心诱导出一个吸引区域。因此，由排斥势束缚的准稳态电子态出现。讨论了这种由场诱导的石墨烯态与通常具有抛物线电子色散的系统之间的差异，并考虑了这些态在石墨烯电子输运和光谱中的可能表现。 显示英文摘要

摘要： 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.
