论文摘要
介绍了条件晶体,是一种周期性结构,该结构具有由两个平板组成的,由两个平板制成,在短时间上持续温度波样振荡。对于局部温度脉冲,研究了温度标量场的复合值分散关系。色散揭示了频率差距,在改变平板热性能的情况下可调节。结果显示了基于石墨烯的调节晶体的范式情况。节制晶体将超晶格的概念扩展到温度波的领域,从而使在上述液氮温度下的流体动力学状态中对超快温度脉冲的连贯控制。
The temperonic crystal, a periodic structure with a unit cell made of two slabs sustaining temperature wave-like oscillations on short time-scales, is introduced. The complex-valued dispersion relation for the temperature scalar field is investigated for the case of a localised temperature pulse. The dispersion discloses frequency gaps, tunable upon varying the slabs thermal properties. Results are shown for the paradigmatic case of a graphene-based temperonic crystal. The temperonic crystal extends the concept of superlattices to the realm of temperature waves, allowing for coherent control of ultrafast temperature pulses in the hydrodynamic regime at above liquid nitrogen temperatures.
