摘要:

我们在这里提出了一个理想的二能级量子系统和超振荡脉冲之间的相互作用的理论分析,就像在https://doi.org/10.1088/2040-8986/abfedf和arXiv:2106.09192中提出并成功合成的那样。作为一个突出的特点,这些脉冲提出了一个高效率的中央超振荡区的不可避免的旁瓣。此外,我们的研究表明,脉冲的有效带宽的增加,在超振荡区域,而不仅仅是一个本地频率高于其最高傅立叶频率分量的外观,在通常的描述超振荡的现象。除了引入有效超带宽的概念外,所提出的结果可能与实验应用相关,并为激光与物质相互作用开辟了新的前景。

英文摘要:

We present here a theoretical analysis of the interaction between an ideal two-level quantum system and a super-oscillatory pulse, like the one proposed and successfully synthesized in https://doi.org/10.1088/2040-8986/abfedf and arXiv:2106.09192. As a prominent feature, these pulses present a high efficiency of the central super-oscillatory region in relation to the unavoidable side-lobes. Besides, our study shows an increase of the effective bandwidth of the pulse, in the super-oscillatory region, and not only the appearance of a local frequency higher than its highest Fourier-frequency component, as in the usual description of the phenomenon of super-oscillations. Beyond introducing the concept of effective super-bandwidth, the presented results could be relevant for experimental applications and opening new perspectives for laser-matter interaction.
