Area metric gravity à la Plebanski: connection, curvature and dynamics
Bianca Dittrich
Area metrics arise as effective description at intermediate scales in a number of approaches to quantum gravity, including string theory, holography and loop quantum gravity. Recen…
Causal structure and light-conical singularities in Lorentzian simplicial quantum gravity
Bianca Dittrich, José Padua-Argüelles
The definition of a Lorentzian gravitational path integral requires specifying which causal struc- tures are admitted off shell. Of particular importance are light-conical singular…
Gravitational wave signatures from area metric gravity
Bianca Dittrich
Area metric theories have been proposed as effective descriptions in a number of quantum gravity approaches: as continuum limit of effective spin foams, as an effective description…
Renormalization group flows in area-metric gravity
Johanna Borissova, Bianca Dittrich, Astrid Eichhorn +1
We put forward the first analysis of renormalization group flows in an area-metric theory, motivated by spin-foam quantum gravity. Area-metric gravity contains the well-known lengt…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Spikes and spines in 4D Lorentzian simplicial quantum gravity
Johanna Borissova, Bianca Dittrich, Dongxue Qu +1
Simplicial approaches to quantum gravity such as quantum Regge calculus and spin foams include configurations where bulk edges can become arbitrarily large while the boundary edges…
Spikes and spines in 3D Lorentzian simplicial quantum gravity
Johanna Borissova, Bianca Dittrich, Dongxue Qu +1
Simplicial approaches to quantum gravity such as Quantum Regge Calculus and Spin Foams include configurations where bulk edges can become arbitrarily large while keeping the length…
De Sitter horizon entropy from a simplicial Lorentzian path integral
Bianca Dittrich, Ted Jacobson, José Padua-Argüelles
The dimension of the Hilbert space of a quantum gravitational system can be written formally as a path integral partition function over Lorentzian metrics. We implement this in a 2…
Area-metric gravity revisited
Johanna N. Borissova, Bianca Dittrich, Kirill Krasnov
Area metrics are an intriguing generalization of length metrics which appears in several quantum-gravity approaches. We describe the space of diffeomorphism-invariant area-metric a…
