Space-time fluctuations and inertia — •Ertan Göklü¹, Abel Camacho², Alfredo Macias², and Claus Lämmerzahl¹ — ¹ZARM - Universität Bremen, Am Fallturm , 28359 Bremen — ²Universidad Autonoma Metropolitana-Iztapalapa, Mexico

The effects upon the Klein-Gordon field of nonconformal stochastic metric fluctuations are analyzed. We characterize the properties of the stochastic fluctuations by a spectral noise density which is parametrized in order to consider different types of noise. These fluctuations lead to an effective mass which is different from the ’bare’ mass. We show that the energy-momentum tensor of the Klein-Gordon field adopts these stochastic fluctuations and that a particle, which is immersed in a region where the tensor is present, sustains decoherence.
