The investigation of boundary charges in asymptotically flat spacetime drew a lot of attention in recent years, which has provided us valuable insight and significantly [...]

A common way to interpret the coordinate invariance of Einstein’s equations is to say that coordinates are a mere gauge redundancy and play no physical [...]

Early dark energy (EDE) is a dark energy-like component in the early universe, which was proposed to solve the Hubble tension, a discrepancy between different [...]

Infrared divergence is a common feature of spinfoam models with a vanishing cosmological constant. The disappearance of divergence at the present of a non-zero cosmological [...]

This talk will be based on the paper arXiv:2301.02930. I will introduce the complex critical points in the 4-dimensional Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam model in [...]

Title: Asymptotically Safe Gravity and the road to observables   Abstract In this seminar I will give a pedagogical introduction to a specific continuum implementation [...]

The Quantum Geometrodynamics program was an early effort to canonically quantize General Relativity in the most straightforward manner possible. The approach involves a formal $3+1$--split [...]

I will start by reviewing a few recent results regarding (nearly-)extremal black holes that come from the non-LQG community. Having done that I'll show that [...]

We construct a master constraint operator on the kinematical Hilbert space of loop quantum gravity representing a set of gauge conditions which fix the densitized [...]
