Bose-Einstein Condensation and Free DKP field
R. Casana, V. Ya. Fainberg, B. M. Pimentel +1
The thermodynamical partition function of the Duffin-Kemmer-Petiau theory is evaluated using the imaginary-time formalism of quantum field theory at finite temperature and path int…

Equivalence of Many-Photon Green Functions in DKP and KGF Statistical Quantum Field Theories
V. Ya. Fainberg, B. M. Pimentel, J. S. Valverde
We prove the equivalence of many-photon Green functions in statistical quantum field Duffin-Kemmer-Petiau (DKP) and Klein-Gordon-Fock (KGF) theories using functional path integral…
