The effective potential of gauged NJL model in magnetic field
I. Brevik, D. M. Gitman, S. D. Odintsov
The formalism, which permits to study the phase structure of gauged NJL-model for arbitrary external fields, is developed. The effective potential in the gauged NJL model in the we…
Path Integrals and Pseudoclassical Description for Spinning Particles in Arbitrary Dimensions
D. M. Gitman
The propagator of a spinning particle in external Abelian field and in arbitrary dimensions is presented by means of a path integral. The problem has different solutions in even an…
Spin Factor in Path Integral Representation for Dirac Propagator in External Fields
D. M. Gitman, S. I. Zlatev
We study the spin factor problem both in and dimensions which are essentially different for spin factor construction. Doing all Grassmann integrations in the correspond…
Chiral symmetry breaking in d=3 NJL model in external gravitational and magnetic fields
D. M. Gitman, S. D. Odintsov, Yu. I. Shil'nov
The phase structure of Nambu-Jona-Lasinio model in curved spacetime with magnetic field is investigated in the leading order of the -expansion and in linear curvature ap…
Proper time and path integral representations for the commutation function
S. P. Gavrilov, D. M. Gitman
On the example of the quantized spinor field, interacting with arbitrary external electromagnetic field, the commutation function is studied. It is shown that a proper time represe…
Vacuum instability in external fields
S. P. Gavrilov, D. M. Gitman
We study particles creation in arbitrary space-time dimensions by external electric fields, in particular, by fields, which are acting for a finite time. The time and dimensional a…
