Motion of a "small body" in non-metric gravity

Kirill Krasnov

We describe "small bodies" in a non-metric gravity theory previously studied by this author. The main dynamical field of the theory is a certain triple of two-forms rather than the…

Plebanski gravity without the simplicity constraints

Kirill Krasnov

In Plebanski's self-dual formulation general relativity becomes SO(3) BF theory supplemented with the so-called simplicity (or metricity) constraints for the B-field. The main dyna…

Cosmological measurements, time and observables in (2+1)-dimensional gravity

C. Meusburger

We investigate the relation between measurements and the physical observables for vacuum spacetimes with compact spatial surfaces in (2+1)-gravity with vanishing cosmological const…

Remarks on Barbero-Immirzi parameter as a field

Alexander Torres-Gomez, Kirill Krasnov

We revisit a propagating torsion gravity theory obtained by introducing a field coupled to the Holst term in the first-order Einstein-Cartan action. The resulting theory has second…

Hamiltonian Analysis of non-chiral Plebanski Theory and its Generalizations

Sergei Alexandrov, Kirill Krasnov

We consider non-chiral, full Lorentz group-based Plebanski formulation of general relativity in its version that utilizes the Lagrange multiplier field Phi with "internal" indices.…

Semiclassical regime of Regge calculus and spin foams

Eugenio Bianchi, Alejandro Satz

Recent attempts to recover the graviton propagator from spin foam models involve the use of a boundary quantum state peaked on a classical geometry. The question arises whether bey…
