We study the production of massive fermions in arbitrary vector and axial-vector classical backgrounds using effective action techniques. A perturbative calculation shows the different features of each field and in particular it is seen that pure temporal axial fields can produce particles whereas it is not possible for a pure vector background. We also analyze from a non-perturbative point of ...
We consider the resonant production of fermions from an oscillating axial background. The classical evolution of the axial field is given by that of a massive pseudovector field, as suggested by the renormalizability of the theory. We look upon both the massive and the massless fermion production from a perturbative point of view. We obtain the corresponding spectrum and angular distributions f...
We develop a color bosonization approach to treatment of QCD gauge field (”gluons”) at low energies in order to derive an effective color action of QCD taking into account the quark chiral anomaly in the case of SU(2) color.. We have found that there exists such a region in the chiral sector of color space, where a gauge field coincides with of chirally rotated vector field, while an induced ax...
the natural frequency and pull-in instability of clamped-clamped nano-actuators in the presence of a dielectric layer are analyzed. the influence of the presence of casimir force, electrostatic force, fringing field effect, axial force, stretching effects and the size effect are taken into account. the governing equation of the dynamic response of the actuator is transformed in a non-dimensiona...
Augmentations to the Euler-Heisenberg Lagrangian (QED one-loop effective action in homogeneous electromagnetic fields) under a constant background axial gauge are examined. Two special configurations admit an exact eigendecomposition, and hence as spectral sum, of augmented Dirac operator: one with magnetic field chiral chemical potential, other electric spatial gauge, which resembles emergent ...
New approach to quantization of the relativistic Majorana field is presented. It based on expansion into eigenfunctions axial momentum -- a novel observable introduced recently. Relativistic invariance used as main guiding principle instead canonical formalism. Hidden structure quantized in form real Clifford algebra Hermitian fermionic operators unveiled. Generators Poincar\'e transformations ...
