An outstanding open issue in our quest for physics beyond Einstein is the unification of
general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading …

Recent advances in classical machine learning have shown that creating models with
inductive biases encoding the symmetries of a problem can greatly improve performance …

The theory of quantum gravity with 4D-tetraquark (quanton) was developed by me in 1996-
2000 [1-3] and it was published in full in 2010 as part of the Superunification theory, which is …

Quantum gravity poses the problem of merging quantum mechanics and general relativity,
the two great conceptual revolutions in the physics of the twentieth century. The loop and …

This article reviews the present status of the spin-foam approach to the quantization of
gravity. Special attention is payed to the pedagogical presentation of the recently-introduced …

The fact that one can associate thermodynamic properties with horizons brings together
principles of quantum theory, gravitation and thermodynamics and possibly offers a window …

The goal of this review is to present an introduction to loop quantum gravity—a background-
independent, non-perturbative approach to the problem of unification of general relativity …

The problem of describing the quantum behavior of gravity, and thus understanding
quantum spacetime, is still open. Loop quantum gravity is a well-developed approach to this …

Over the past three decades, black holes have played an important role in quantum gravity,
mathematical physics, numerical relativity and gravitational wave phenomenology …

The discovery in the early 1970s that black holes radiate as black bodies has radically
affected our understanding of general relativity, and offered us some early hints about the …
