Solutions in Liouville theory on dS and AdS backgrounds
Damir Sadekov
We find exact solutions of a Liouville-type scalar field theory on -dimensional de Sitter and anti-de Sitter backgrounds, treating the geometry as nondynamical. Using the embedd…

Global quenches and correlator dynamics in de Sitter space
Ivan A. Belkovich, Damir Sadekov, Gleb S. Zverev
We study non-equilibrium initial states of quantum fields in curved space-time and develop a framework for describing global quenches as unitary perturbations of the initial densit…

Effective graviton mass in de Sitter space
Damir Sadekov
We calculate the effective mass of gravitational perturbations induced by the interaction of the classical gravitational field with quantum matter in the background of the Poincaré…
