Simple model for quantum general relativity from loop quantum gravity [PDF]
, 2010 New progress in loop gravity has lead to a simple model of a 'general-covariant quantum field theory'. I sum up the definition of the model in self-contained form, in terms accessible to those outside the subfield.

Quantum tests of the foundations of general relativity [PDF]
Classical and Quantum Gravity, 1998 The role of the equivalence principle in the context of non-relativistic quantum mechanics and matter wave interferometry, especially atom beam interferometry, will be discussed. A generalised form of the weak equivalence principle which is capable of covering quantum phenomena too, will be proposed.

Unconventional reconciliation path for quantum mechanics and general relativity
IET Quantum Communication, 2022 Physics in general is successfully governed by quantum mechanics at the microscale and principles of relativity at the macroscale. Any attempts to unify them using conventional methods have somewhat remained elusive for nearly a century up to the present

Deformed symmetries from quantum relational observables [PDF]
, 2007 Deformed Special Relativity (DSR) is a candidate phenomenological theory to describe the Quantum Gravitational (QG) semi-classical regime. A possible interpretation of DSR can be derived from the notion of deformed reference frame.

A generalized quantum relative entropy
Advances in Mathematics of Communications, 2020 We propose a generalization of the quantum relative entropy by considering the geodesic on a manifold formed by all the invertible density matrices \begin{document}$ \mathcal{P} $\end{document} . This geodesic is defined from a deformed exponential function \begin{document}$ \varphi $\end{document} which allows to work with a wider class of ...

Clocks without “Time” in Entangled-State Experiments
Entropy, 2020 Entangled states of light exhibit measurable correlations between light detections at separated locations. These correlations are exploited in entangled-state quantum key distribution.

Preferred foliation effects in Quantum General Relativity [PDF]
, 2010 We investigate the infrared (IR) effects of Lorentz violating terms in the gravitational sector using functional renormalization group methods similar to Reuter and collaborators.

The Value of Singularities [PDF]
, 1995 We point out that spacetime singularities play a useful role in gravitational theories by eliminating unphysical solutions. In particular, we argue that any modification of general relativity which is completely nonsingular cannot have a stable ground ...
