The Physics of Negative Energy Densities
Adam D. Helfer
I review some recent results showing that the physics of negative energy densities, as predicted by relativistic quantum field theories, is more complicated than has generally been…

The electromagnetic field near a dielectric half-space
Adam D. Helfer, Andrew S. I. D. Lang
We compute the expectations of the squares of the electric and magnetic fields in the vacuum region outside a half-space filled with a uniform non-dispersive dielectric. This gives…

Negative Energy Densities and the Limit of Classical Space-Time
Adam D. Helfer
Although negative energy densities are predicted by relativistic quantum field theories, I present an argument that an "operational" positivity still holds: the energy in a region,…
