Negative Energy Density States for the Dirac Field in Flat Spacetime
arXiv:gr-qc/9806064 · doi:10.1103/PhysRevD.57.3484
Abstract
Negative energy densities in the Dirac field produced by state vectors that are the superposition of two single particle electron states are examined. I show that for such states the energy density of the field is not bounded from below and that the quantum inequalities derived for scalar fields are satisfied. I also show that it is not possible to produce negative energy densities in a scalar field using state vectors that are arbitrary superpositions of single particle states.
