Continuous measurement of intrinsic time by fermions

  • 1. Heidelberg Univ. (Germany, F.R.). Inst. fuer Theoretische Physik

Description

It is demonstrated how classical properties of the intrinsic time variable in minisuperspace of quantum gravity would emerge in the sense of a continuous measurement process solely through interaction with fermionic degrees of freedom. This measurement is much less effective than that by bosons considered in a previous paper. Continuous measurement by fermions would not lead to classical properties for values of intrinsic time near the singularity of Friedmann universe. It is argued that this result remains true for the full quantum theory of gravity. (author)
