声电磁混合超材料超导体

Hybrid acousto-electromagnetic metamaterial superconductors

Igor I. Smolyaninov, Vera N. Smolyaninova

摘要:

最近的理论和实验研究表明,电磁超材料的方法是能够大幅提高复合超材料超导体的临界温度Tc。这一进展是通过设计超材料的频率相关介电响应函数实现的。在这里,我们通过引入混合声电磁双曲超材料超导体的概念来进一步扩展这种方法,由于人工设计的Eliashberg电子-声子谱密度函数的宽带发散,该超材料超导体预计将表现出强烈增强的超导特性。在此基础上,提出了一种由LSCO/STO纳米合金制成的声电磁混合超材料。

英文摘要:

Recent theoretical and experimental studies demonstrated that an electromagnetic metamaterial approach is capable of drastically increasing the critical temperature Tc of composite metamaterial superconductors. This progress was achieved by engineering the frequency-dependent dielectric response function of the metamaterial. Here we further extend this approach by introducing the concept of hybrid acousto-electromagnetic hyperbolic metamaterial superconductors, which are projected to exhibit strongly enhanced superconducting properties due to artificially engineered broadband divergency of the Eliashberg electron-phonon spectral density function. Based on the developed approach, a hybrid acousto-electromagnetic metamaterial is proposed, which is made of LSCO/STO nano-alloy.
