Dressed metric predictions revisited
Wojciech Kamiński, Maciej Kolanowski, Jerzy Lewandowski
It was recently shown that the volume operator of loop quantum cosmology (LQC) and all its positive powers are ill-defined on physical states. In this paper, we investigate how it…
Extremal horizons stationary to the second order: new constraints
Maciej Kolanowski, Jerzy Lewandowski, Adam Szereszewski
We consider non-expanding shear free (NE-SF) null surface geometries embeddable as extremal Killing horizons to the second order in Einstein vacuum spacetimes. A NE-SF null surface…
On backreaction effects in geometrical destabilisation of inflation
Oskar Grocholski, Marcin Kalinowski, Maciej Kolanowski +3
We study the geometrical instability arising in multi-field models of inflation with negatively-curved field space. We analyse how the homogeneous background evolves in presence of…
