Quantum field theory in the Weyl-Wigner representation
Emilio Santos
The Wigner representation for quantum mechanics of particles is generalized to Bose fields. The standard Hilbert space quantization becomes, via the Weyl transform, a quantization…
Are Bell's conditions for local realism general enough?
Emilio Santos
Bell conditions for local realism are critically revisited. In particular for optical experiments I criticize Bell's proposed response of detectors to signals as extremely idealize…
The quantum theory of the electromagnetic field in the Weyl-Wigner representation as a local realistic model
Emilio Santos
I revisit the Wigner (or Weyl-Wigner, WW) representation of the quantum electromagnetic field. I show that, assuming that Fock states are just mathematical concepts devoid of physi…
The quantum electromagnetic field in the Weyl-Wigner representation
Emilio Santos
The quantum electromagnetic (EM) field is formulated in the Weyl-Wigner representation (WW), which is equivalent to the standard Hilbert space one (HS). In principle it is possible…
Effects of the quantum vacuum at a cosmic scale and of dark energy
Emilio Santos
The Einstein equation in a semi-classical approximation is applied to a spherical region of the universe, with the stress-energy tensor consisting of the mass density and pressure…
