New Action Principle for General Relativity

Kirill Krasnov

General Relativity can be reformulated as a diffeomorphism invariant SU(2) gauge theory. A new action principle for this "pure connection" formulation of GR is described.

A Unified Theory of Non-Linear Electrodynamics and Gravity

Alexander Torres-Gomez, Kirill Krasnov, Carlos Scarinci

We describe a class of unified theories of electromagnetism and gravity. The Lagrangian is of the BF type, with a potential for the B-field, the gauge group is U(2) (complexified).…

Quantum dynamics of the Einstein-Rosen wormhole throat

Gabor Kunstatter, Jorma Louko, Ari Peltola

We consider the polymer quantization of the Einstein wormhole throat theory for an eternal Schwarzschild black hole. We numerically solve the difference equation describing the qua…

Analogue Cosmological Particle Creation: Quantum Correlations in Expanding Bose Einstein Condensates

Angus Prain, Serena Fagnocchi, Stefano Liberati

We investigate the structure of quantum correlations in an expanding Bose Einstein Condensate (BEC) through the analogue gravity framework. We consider both a 3+1 isotropically exp…

Semiclassical Gravity in the Far Field Limit of Stars, Black Holes, and Wormholes

Eric D. Carlson, Paul R. Anderson, Alessandro Fabbri +3

Semiclassical gravity is investigated in a large class of asymptotically flat, static, spherically symmetric spacetimes including those containing static stars, black holes, and wo…

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…
