摘要:

真空涨落是量子化场的一个基本特征。通常认为,与真空涨落有关的观测需要一个与其他影响很好隔离的系统。在这项工作中,我们证明了量子真空的影响已经可以发生在湿化学制备的简单胶体纳米组装。我们声称,在零点水平的电磁场波动饱和的吸收染料分子自组装在等离子体纳米谐振器的表面。为了发生这种效应,不需要达到等离子体激元和激子之间的强耦合状态。真空诱导饱和(VISA)的这种有趣的效果进行了讨论,在一个简单的量子光学图片,并证明了通过比较混合金核染料壳纳米棒的电磁模拟的光谱。

英文摘要:

Vacuum fluctuations are a fundamental feature of quantized fields. It is usually assumed that observations connected to vacuum fluctuations require a system well isolated from other influences. In this work, we demonstrate that effects of the quantum vacuum can already occur in simple colloidal nano-assemblies prepared by wet chemistry. We claim that the electromagnetic field fluctuations at the zero-point level saturate the absorption of dye molecules self-assembled at the surface of plasmonic nano-resonators. For this effect to occur, reaching the strong coupling regime between the plasmons and excitons is not required. This intriguing effect of vacuum-induced saturation (VISA) is discussed within a simple quantum optics picture and demonstrated by comparing the optical spectra of hybrid gold-core dye-shell nanorods to electromagnetic simulations.
