Equivalence of many-photon Green's functions in the Duffin-Kemmer-Petiau and Klein-Gordon-Fock statistical quantum field theories
(Consultants Bureau, 2004-07-01)
Using the functional integral formalism for the statistical generating functional in the statistical (finite temperature) quantum field theory, we prove the equivalence of many-photon Greens functions in the Duffin-Kennner-Petiau ...

Quantum q-field theory: Q-Schrödinger and q-Klein-Gordon fields
(Europhysics Letters, 2017-06)
We show how to deal with the generalized q-Schrödinger and q-Klein-Gordon fields in a variety of scenarios. These q-fields are meaningful at very high energies (TeVs) for high ones (GeVs) for and at low energies (MeVs) for ...
Regular spinors and fermionic fields
(2021-06-28)
Bearing in mind the Lounesto spinor classification, we connect the expansion coefficients of well behaved fermionic quantum field, i.e., a local field within a full Lorentz covariant theory, with and only with a given ...
Aspects of quantum information in finite density field theory
(Springer, 2021-03)
We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero chemical potential, and work in 1 + 1 ...
Consistent higher derivative quantum field theory: A model without tachyons and ghosts
(1996-12-01)
We present a higher derivative gauge theory in (2 + 1) dimensions which can have its parameters suitably tuned in order to become a consistent quantum field theory, in the sense that both tachyons and ghosts are absent ...
