Surprises of Klein paradox
T. R. Ahmadov, E. T. Akhmedov, V. I. Lapushkin
We consider second quantized dimensional Dirac fermions with mass in background electric fields. This theory mimics the following situations. We consider two parallel cap…
On radiation from hyperbolic motion, behavior of electromagnetic fields, and coordinate transformations at infinity
E. T. Akhmedov, M. N. Milovanova
We show explicitly that radiation from a uniformly accelerating charge escapes outside Rindler wedge, while within Rindler wedge there is no flux through infinity, neither in the M…
Sine-Gordon solitons in AdS, dS and other hyperbolic spaces
E. T. Akhmedov, D. V. Diakonov
We find infinitely many soliton-like solutions in a deformation of the sine-Gordon theory in -dimensional (anti-de Sitter) spacetime for , as well as s…
Does Schwinger's value for the current of created pairs gets modified for long and strong enough pulse?
E. T. Akhmedov, P. S. Zavgorodny
We determine the parametric conditions (pulse strength and duration) under which Schwinger's prediction for the pair-creation current - and therefore the probability - is significa…
Lessons from the Klein paradox
E. T. Akhmedov, D. V. Diakonov, V. I. Lapushkin +1
We re-examine the Klein paradox from a many-particle perspective in quantum field theory. Specifically, we compute the expectation value of the particle current induced by a suffic…
Once more about radiation from uniformly accelerating charge
E. T. Akhmedov, M. N. Milovanova
We consider an electric charge uniformly accelerating along direction and moving with constant velocity along direction. We show that in the co-accelerating along direc…
