摘要:
当系统尺寸小于能量载体的平均自由程时,球面传输被认为是能量传输的极限。在此,我们预测了一种超球面辐射热传输模式,该模式在稀疏等离子体纳米颗粒链中超越了这一极限。这种异常模式表现出有效热导率的超线性 scaling(k ~ L^1.5),其起源是通过腔体引导模式放大长程相互作用。我们的结果建立了一个超快光子热传输的框架,并为量子和纳米系统中的热管理、信息处理和能量传输开辟了新途径。
英文摘要:
Ballistic transport, realized when the system size is smaller than the mean free path of energy carriers, is traditionally regarded as the ultimate limit for energy transfer. Here, we predict a superballistic radiative heat transport regime that surpasses this limit in dilute chains of plasmonic nanoparticles confined within cavities. This anomalous regime exhibits superlinear scaling of the effective thermal conductivity (k ~L^1.5) and originates from the amplification of long-range interactions mediated by cavity-guided modes. Our results establish a framework for ultrafast photonic heat transport and open pathways for thermal management, information processing and energy transfer in quantum and nanoscale systems.
