Spinfoams: Foundations

Jonathan Engle, Simone Speziale

Spinfoams provide a framework for the dynamics of loop quantum gravity that is manifestly covariant under the full four-dimensional diffeomorphism symmetry group of general relativ…

Holonomy corrected Schwarzschild black hole lensing

A. R. Soares, C. F. S. Pereira, R. L. L. Vitória

In the present work, we theoretically investigate gravitational lensing in the spacetime of a holonomy corrected Schwarzschild black hole. Analytical expressions for the light defl…

On the geometry of the black-to-white hole transition within a single asymptotic region

Muxin Han, Carlo Rovelli, Farshid Soltani

We write explicitly the complete Lorentzian metric of a singularity-free spacetime where a black hole transitions into a white hole located in its same asymptotic region. In partic…

Quasi-equilibrium configurations of binary systems of dark matter admixed neutron stars

Hannes R. Rüter, Violetta Sagun, Wolfgang Tichy +1

Using an adapted version of the SGRID code, we construct for the first time consistent quasi-equilibrium configurations for a binary system consisting of two neutron stars in which…

Complex critical points in Lorentzian spinfoam quantum gravity: 4-simplex amplitude and effective dynamics on double- complex

Muxin Han, Hongguang Liu, Dongxue Qu

The complex critical points are analyzed in the 4-dimensional Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam model in the large- regime. For the 4-simplex amplitude, ta…
