27. Towards Quantization of Horava Gravity

Jury Radkovski (Perimeter Institute, McMaster University)

Horava Gravity is a field-theoretic model that shares many properties of GR. Namely it has metric as a basic degree of freedom and possesses spatial diffeomorphisms, as well as global time reparameterizations, as its symmetries. The feature of the model is the potentially much improved high energy behavior at the expense of forbidding the symmetry of local time reparameterizations and...

8. Quantum nature of spacetime curvature in the deep quantum regime of a black hole

We investigate the quantum behavior of the Kretschmann curvature invariant $\mathcal{K}$ in the deep quantum regime near black hole singularities, where the classical expression diverges as $r^{-6}$ as $r \to 0$. Our goal is to understand whether this singular behavior persists under a quantum mechanical treatment. Due to the involvement of both first- and second-order time derivatives of...

12. Physical Foundations of Schrödinger and Dirac Wave Equations and their Implications to Quantum Cosmology and Quantum Gravity

Siavash Sohrab (Northwestern University)

Abstract
Introduction of stochastic definitions of universal Planck and Boltzmann constants (h, k) reveals hydrodynamic origins of both quantum mechanics and quantum field theory. Also, new perspectives regarding the quantum nature of internal atomic (spacetime, mass) versus external (space, time, mass), black hole, white hole, and Dirac anti-matter are discussed. The temperature limits...

15. Wormholes in $f(R,T_{ab}T^{ab})$ modified-gravity theory

Vladislav Ganiyev (Brock University)

31/10/2025, 17:15

In this presentation, we investigate traversable wormhole spacetimes within the context of $f(R,T_{ab}T^{ab})$ modified-gravity theory. By considering a linear form of the function, we demonstrate the existence of numerous wormhole solutions where the matter fields satisfy all energy conditions. However, due to the lack of natural localization of these solutions, it is necessary to match them...

39. Conformal Cores of Quantum Black Holes in Quadratic Gravity

Ruolin Liu (University of Waterloo, Perimeter Institute)

31/10/2025, 17:30

We explore the possibility that quadratic gravity, as a renormalizable theory, describes the interior of quantum black holes. We find new exact power-law solutions to pure quadratic gravity under spherical symmetry, which are complex valued. The resulting solutions, dubbed powerballs, are horizonless compact objects that become Schwarzschild-like a small distance (of the order of the Planck...
