摘要:

具有超强光-物质相互作用的腔光子谐振器在半导体和超导系统中显示出操纵具有可控物理性质的腔量子电动力学基态的能力,引起了人们的极大兴趣。在这里,我们回顾了一系列的实验,旨在探测超强光-物质耦合制度,真空拉比分裂$Ω$是可比的裸跃迁频率$ω$。我们提出了一个新的平台,其中的二维电子气(2DEG)的朗道能级间跃迁强烈耦合到深亚波长分裂环谐振器的基本模式在毫米波范围内工作。记录高值的归一化光-物质耦合比$\fracΩω= 0.89$达到和系统出现高度可扩展到微波范围内。

英文摘要:

Cavity photon resonators with ultrastrong light-matter interactions are attracting interest both in semiconductor and superconducting systems displaying the capability to manipulate the cavity quantum electrodynamic ground state with controllable physical properties. Here we review a series of experiments aimed at probing the ultrastrong light-matter coupling regime, where the vacuum Rabi splitting $Ω$ is comparable to the bare transition frequency $ω$ . We present a new platform where the inter-Landau level transition of a two-dimensional electron gas (2DEG) is strongly coupled to the fundamental mode of deeply subwavelength split-ring resonators operating in the mm-wave range. Record-high values of the normalized light-matter coupling ratio $\fracΩω= 0.89$ are reached and the system appears highly scalable far into the microwave range.
