Bose-einstein condensation and free DKP field
Sifuentes, Rodolfo Alvan Casana; Fainberg, Vladimir Yakovlevich; Escobar, Bruto Max Pimentel; Salvador, Juan Segundo Valverde (2003)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 integral methods. The DKP partition function ... -
Equivalence of many photon green functions in DKP and KGF statistical quantum field theories
Fainberg, Vladimir Yakovlevich; Escobar, Bruto Max Pimentel; Salvador, Juan Segundo Valverde (2004)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 formalism for partition functional in ...
