Abstract
The phenomenon of macroscopic quantum coherence is examined within the framework of a two-level system coupled to an Ohmic bath. A bound is obtained for the temperature above which the macroscopic variable cannot display the oscillatory behavior characteristic of quantum coherence. Different approximations for the dynamical behavior of the macroscopic variable in the low-dissipation limit are compared.
