Abstract

We address the problem of finding a system in which there would be measurable quantum gravitational effects. Following standard quantum-field methods, we have calculated the first-order radiative correction of graviton exchange on the binding energy of an electron with an ultra cold superfluid droplet of 4He with mass about the Planck mass. For two 4He droplets with a mass difference of about one microgram, we show that the relative difference in the binding energies is about one percent.
