超导电路中模拟宇宙学粒子的产生

Analog cosmological particle generation in a superconducting circuit

Zehua Tian, Jiliang Jing, Andrzej Dragan

摘要:

我们提出了一种基于直流超导量子干涉器件(dc-SQUID)的波导传输线的使用,并证明了在这种传输线中的节点通量的行为在膨胀(或收缩)的宇宙中的量子场以相同的方式。我们展示了如何检测模拟宇宙粒子的产生,并分析其可行性与电流电路量子电动力学(cQED)技术。我们的设置在原则上铺平了一条新的途径,探索模拟量子引力效应。

英文摘要:

We propose the use of a waveguidelike transmission line based on direct-current superconducting quantum interference devices (dc-SQUID) and demonstrate that the node flux in this transmission line behaves in the same way as quantum fields in an expanding (or contracting) universe. We show how to detect the analog cosmological particle generation and analyze its feasibility with current circuit quantum electrodynamics (cQED) technology. Our setup in principle paves a new way for the exploration of analogue quantum gravitational effects.
