在最近的一篇论文中，贝克和麦基 [C.贝克，M.C. Mackey, astro-ph/0603397] 认为我们在论文 [Ph. Mackey, astro-ph/0603397] 中给出的论点。 Jetzer，N. Straumann，物理学家。莱特。 B 606 (2005) 77, astro-ph/0411034] 反驳他们的说法，即可以通过约瑟夫森结的噪声测量在实验室中发现暗能量是不正确的。特别是，他们强调约瑟夫森结中测量的噪声频谱是波动耗散定理的结果，而我们的论点是基于平衡统计力学。在这篇文章中，我们表明涨落耗散关系不依赖于真空（零点）能量的任何变化，因此，正如我们在之前的论文中已经得出的结论，暗能量与所提出的测量无关。
In a recent paper Beck and Mackey [C. Beck, M.C. Mackey, astro-ph/0603397] argue that the argument we gave in our paper [Ph. Jetzer, N. Straumann, Phys. Lett. B 606 (2005) 77, astro-ph/0411034] to disprove their claim that dark energy can be discovered in the Lab through noise measurements of Josephson junctions is incorrect. In particular, they emphasize that the measured noise spectrum in Josephson junctions is a consequence of the fluctuation dissipation theorem, while our argument was based on equilibrium statistical mechanics. In this note we show that the fluctuation dissipation relation does not depend upon any shift of vacuum (zero-point) energies, and therefore, as already concluded in our previous paper, dark energy has nothing to do with the proposed measurements.
