Electromagnetic dark energy
Christian Beck, Michael C. Mackey
We introduce a new model for dark energy in the universe in which a small cosmological constant is generated by ordinary electromagnetic vacuum energy. The corresponding virtual ph…
Measurability of vacuum fluctuations and dark energy
Christian Beck, Michael C. Mackey
Vacuum fluctuations of the electromagnetic field induce current fluctuations in resistively shunted Josephson junctions that are measurable in terms of a physical power spectrum. I…
Laboratory tests on dark energy
Christian Beck
The physical nature of the currently observed dark energy in the universe is completely unclear, and many different theoretical models co-exist. Nevertheless, if dark energy is pro…
Could dark energy be measured in the lab?
Christian Beck, Michael C. Mackey
The experimentally measured spectral density of current noise in Josephson junctions provides direct evidence for the existence of zero-point fluctuations. Assuming that the total…
Chaotic scalar fields as models for dark energy
Christian Beck
We consider stochastically quantized self-interacting scalar fields as suitable models to generate dark energy in the universe. Second quantization effects lead to new and unexpect…
