Characterization of the symmetries of non ommutative space-times and quantum field theory endowed with k-Poincaré symmetries |
There has been much interest, in the past few years, in the $\kappa$-Poincar\'e/$\kappa$-Minkowski framework as a scenario for a deformation of Poincar\'e a symmetries. I will discuss a Noether analysis in $\kappa$-Minkowski space-time in which the 10 generators of the $\kappa$-Poincar\'e algebra lead to 10 conserved charges. I will also report previous results on the quantization of scalar field in the same $\kappa$-Poincar\'e/$\kappa$-Minkowski context, imposing that $\kappa$-Poincar\'e acts covariantly on the Fock-space of the theory. And I will also comment on possible applications in astrophysics, cosmology. |

Stepping out of Homogeneity in Loop Quantum Cosmology, II Part: introducing inhomeneities into a Bianchi IX model in LQG |
We study the model proposed by Rovelli and Vidotto in arXiv:0805.4585 [gr-qc] and we outline how degrees of freedom representing inhomogeneities and anisotropies are present in this model. For this purpose, we use the Bianchi IX model and we introduce anisotropies in a perturbative way, both at the classical and at the quantum level. |
