On two approaches to quantization in strong background fields
E. T. Akhmedov, K. A. Kazarnovskii
There are two ways to quantize free (gaussian) theory in strong background fields. In one of them, which we refer to as the Heisenberg approach, the mode functions are defined once…

On the relevance of quantum corrections to the matter stress-energy tensor in eternally expanding universes
E. T. Akhmedov, A. V. Anokhin, K. A. Kazarnovskii
We study a toy-model of continuous infinite expansion of space-time with the flat start. We use as the gravitational background a conformaly flat metric with an exponentially growi…

Loop corrections to the current of created pairs in the lengthy electric pulse
E. T. Akhmedov, P. S. Zavgorodny, D. I. Sadekov +1
We discuss loop-corrections to the electric current produced by strong and lengthy electric pulse. Namely we calculate one loop contribution to the electric current, distinguishing…
