“Millikan oil drops” as quantum transducers between electromagnetic and gravitational radiation
نویسنده
چکیده
Pairs of Planck-mass-scale drops of superfluid helium coated by electrons (i.e., “Millikan oil drops”), when levitated in the presence of strong magnetic fields and at low temperatures, can be efficient quantum transducers between electromagnetic (EM) and gravitational (GR) radiation. A Hertz-like experiment, in which EM waves are converted at the source into GR waves, and then back-converted at the receiver from GR waves back into EM waves, should be practical to perform. This would open up observations of the gravity-wave analog of the Cosmic Microwave Background from the extremely early Big Bang, and also communications directly through the interior of the Earth.

The generation, as well as the detection, of gravitational radiation by means of charged superfluids is considered. One example of such a “charged superfluid” consists of a pair of Planck-mass-scale, ultracold “Millikan oil drops,” each with a single electron on its surface, in which the oil of the drop is replaced by superfluid helium. When levitated in a magnetic trap, and subjected to microw...

متن کامل, e . g . , superconducting transducers between electromagnetic and gravitational radiation ?
One of the conceptual tensions between quantum mechanics (QM) and general relativity (GR) arises from the clash between the spatial nonseparability of entangled states in QM, and the complete spatial separability of all physical systems in GR, i.e., between nonlocality implied by the superposition principle, and locality implied by the equivalence principle. Experimental consequences of this co...
