论文摘要
将量子材料放入光腔中，为通过弱和强的光结合耦合提供了一个独特的平台，用于控制物质的量子合作特性。在这里，我们报告了相关的固态材料中金属对绝缘子相变的可逆腔控制的实验证据。我们将1T-TAS $ _ {2} $的电荷密度波材料嵌入到低温可调的Terahertz腔中，并表明与样品温度发生较大变化相关的导电和绝缘行为之间的切换是通过机械调整腔体镜子和它们的对准之间的距离而获得的。观察到的大型热修饰表明percell样情况，其中腔的光谱曲线修改了材料与外部电磁场之间的能量交换。我们的发现提供了通过工程电磁环境来控制量子材料的热力学和宏观运输特性的机会。
Placing quantum materials into optical cavities provides a unique platform for controlling quantum cooperative properties of matter, via both weak and strong light-matter coupling. Here we report the experimental evidence of reversible cavity control of a metal-to-insulator phase transition in a correlated solid-state material. We embed the charge density wave material 1T-TaS$_{2}$ into cryogenic tunable terahertz cavities and show that a switch between conductive and insulating behaviors, associated with a large change in the sample temperature, is obtained by mechanically tuning the distance between the cavity mirrors and their alignment. The large thermal modification observed is indicative of a Purcell-like scenario in which the spectral profile of the cavity modifies the energy exchange between the material and the external electromagnetic field. Our findings provide opportunities for controlling the thermodynamics and macroscopic transport properties of quantum materials by engineering their electromagnetic environment.
