De Sitter space as BRST invariant coherent state of gravitons
Lasha Berezhiani, Gia Dvali, Otari Sakhelashvili
The -matrix formulation indicates that a consistent embedding of de Sitter state in quantum gravity is possible exclusively as an excited quantum state constructed on top of a v…
Background Field Method and Initial-Time Singularity for Coherent States
Lasha Berezhiani, Giordano Cintia, Michael Zantedeschi
The background field method is adopted for studying the dynamics of coherent states within an interacting scalar field theory. Focusing on a coherent state that corresponds to the…
Core Fragmentation in Simplest Superfluid Dark Matter Scenario
Lasha Berezhiani, Giordano Cintia, Max Warkentin
We study the structure of galactic halos within a scalar dark matter model, endowed with a repulsive quartic self-interaction, capable of undergoing the superfluid phase transition…
