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 discuss 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. The parameter values relevant for early-universe axion cosmology are accessible with present day%26apos;s achievements in nanotechnology.
