Semiclassical Analysis of Constrained Quantum Systems
Artur Tsobanjan
Exact procedures that follow Dirac's constraint quantization of gauge theories are usually technically involved and often difficult to implement in practice. We overview an "effect…
In, Through and Beyond the Planck Scale
Leonardo Modesto, Isabeau Prémont-Schwarz
In this paper we have recalled the semiclassical metric obtained from a classical analysis of the loop quantum black hole (LQBH). We show that the regular Reissner-Nordström-like m…
Beyond the Planck scale
Steven B. Giddings
I outline motivations for believing that important quantum gravity effects lie beyond the Planck scale at both higher energies and longer distances and times. These motivations ari…
2-Group Representations for Spin Foams
Aristide Baratin, Derek K. Wise
Just as 3d state sum models, including 3d quantum gravity, can be built using categories of group representations, "2-categories of 2-group representations" may provide interesting…
Deformed Maxwell Algebras and their Realizations
Joaquim Gomis, Kiyoshi Kamimura, Jerzy Lukierski
We study all possible deformations of the Maxwell algebra. In D=d+1\neq 3 dimensions there is only one-parameter deformation. The deformed algebra is isomorphic to so(d+1,1)\oplus…
Cosmological consequences of the NonCommutative Geometry Spectral Action
Mairi Sakellariadou
Cosmological consequences of the noncommutative geometry spectral action are presented. Neglecting the nonminimal coupling of the Higgs field to the curvature, background cosmology…
