复合氧化物异质结构腔约瑟夫森等离子体

Yannis Laplace, Stephanie Fernandez-Pena, Stefano Gariglio, Jean-Marc Triscone, Andrea Cavalleri

摘要:

我们讨论了如何复杂的氧化物异质结构,包括高Tc超导铜氧化物可以用来实现一个阵列的亚毫米腔,支持约瑟夫森等离子体激元。这些腔有几个有吸引力的功能,为新型的轻物质相互作用的研究,我们表明,他们促进太赫兹频率辐射和约瑟夫森等离子体之间的“超强”耦合。约瑟夫森等离子体激元的腔电动力学允许操纵超导序参量相位相干性。作为一个例子,我们讨论了它如何可以用来冷却超导相位波动与光。

英文摘要:

We discuss how complex-oxide heterostructures that include high-Tc superconducting cuprates can be used to realize an array of sub-millimeter cavities that support Josephson plasmon polaritons. These cavities have several attractive features for new types of light matter interaction studies and we show that they promote "ultrastrong" coupling between THz frequency radiation and Josephson plasmons. Cavity electrodynamics of Josephson plasmons allows to manipulate the superconducting order-parameter phase coherence. As an example, we discuss how it could be used to cool superconducting phase fluctuations with light.
