Energy-momentum tensor in thermal strong-field QED with unstable vacuum
S. P. Gavrilov, D. M. Gitman
The mean value of the one-loop energy-momentum tensor in thermal QED with electric-like background that creates particles from vacuum is calculated. The problem differes essentiall…
Pseudoclassical description of scalar particle in non-Abelian background and path-integral representations
R. Fresneda, D. Gitman
Path-integral representations for a scalar particle propagator in non-Abelian external backgrounds are derived. To this aim, we generalize the procedure proposed by Gitman and Schv…
Path integral representations in noncommutative quantum mechanics and noncommutative version of Berezin-Marinov action
D. M. Gitman, V. G. Kupriyanov
It is known that actions of field theories on a noncommutative space-time can be written as some modified (we call them -modified) classical actions already on the commutative s…
Comments on spin operators and spin-polarization states of 2+1 fermions
S. P. Gavrilov, D. M. Gitman, J. L. Tomazelli
In this brief article we discuss spin polarization operators and spin polarization states of 2+1 massive Dirac fermions and find a convenient representation by the help of 4-spinor…
