Incompatibility of the Observer-Based Vacuum with Canonical Quantum Field Theory

摘要

Three new stationary coordinate systems in flat space-time, the last of six possible types, are described. The vacuum state found by canonical quantization of the scalar field in two of these systems is identical to that of Rindler coordinates, yet detectors at rest in these systems are excited in different amounts. A definition of the vacuum based on these detectors is, therefore, incompatible with canonical quantum field theory. The vacuum of the third system is identical to the Minkowski coordinate vacuum; thus, there are only two different vacua in flat space-time. (ERA citation 06:001521)
