On (dis)agreement between different methods of calculation of the imaginary part of the effective action in expanding space-times
E. T. Akhmedov, I. A. Belkovich, D. V. Diakonov +1
We consider two approaches to calculate imaginary parts of effective actions in expanding space-times. While the first approach uses Bogolyubov coefficients, the second one uses th…

Complex effective actions and gravitational pair creation
E. T. Akhmedov, D. V. Diakonov, C. Schubert
We use different methods to calculate the imaginary part of the gravitational effective action due to a massless scalar field, with a view on perturbative vs. non-pertubative and t…

Free energy and entropy in Rindler and de Sitter space-times
E. T. Akhmedov, D. V. Diakonov
We investigate the free energy and entropy of the Gaussian massive scalar field theory in the static de Sitter space-time for arbitrary temperature. For the inverse temperatures of…
