标题： Axion physics in a Josephson junction environment

摘要： 我们表明，近期基于约瑟夫森结、超导量子干涉装置（SQUID）和耦合约瑟夫森量子比特的实验可以从轴子暗物质物理学的角度来解释早期宇宙学，这意味着它们能够类比模拟早期宇宙轴子物理学。 我们提出了新的实验设置，在共振约瑟夫森结环境中可以测试类似于轴子相互作用，其性质与最近测试两个耦合约瑟夫森量子比特量子纠缠的实验相似。 我们指出，早期宇宙轴子宇宙学相关的参数值可以通过当今纳米技术的成就来实现。 显示英文摘要

摘要： We show that recent experiments based on Josephson junctions, SQUIDS, and coupled Josephson qubits have a cosmological interpretation in terms of axionic dark matter physics, in the sense that they allow for analogue simulation of early-universe axion physics. We propose new experimental setups in which SQUID-like axionic interactions in a resonant Josephson junction environment can be tested, similar in nature to recent experiments that test for quantum entanglement of two coupled Josephson qubits. We point out that the parameter values relevant for early-universe axion cosmology are accessible with present day's achievements in nanotechnology.
