Bouncing Universe in Loop Quantum Gravity: full theory calculation
Marcin Kisielowski
In Loop Quantum Gravity mathematically rigorous models of full quantum gravity were proposed. In this paper we study a cosmological sector of one of the models describing quantum g…
Properties of the Rovelli-Smolin-DePietri volume operator in the spaces of monochromatic intertwiners
Marcin Kisielowski
We study some properties of the Rovelli-Smolin-DePietri volume operator in loop quantum gravity, which significantly simplify the diagonalization problem and shed some light on the…
Spin-foam model for gravity coupled to massless scalar field
Marcin Kisielowski, Jerzy Lewandowski
A spin-foam model is derived from the canonical model of Loop Quantum Gravity coupled to a massless scalar field. We generalized to the full theory the scheme first proposed in the…
Operator Spin Foam Models
Benjamin Bahr, Frank Hellmann, Wojciech Kamiński +2
The goal of this paper is to introduce a systematic approach to spin foams. We define operator spin foams, that is foams labelled by group representations and operators, as the mai…
