Book cover: Generally Covariant Quantum TheoryGenerally Covariant Quantum Theory
by - viXra ,
The intention of this book is to dig deep in the first principles of physics and develop a relativistic quantum theory from scratch. By this, I mean a theory for the so-called elementary particles which constitute building blocks of nature ...

Book cover: Quantum Einstein GravityQuantum Einstein Gravity
by - arXiv ,
We give a pedagogical introduction to the basic ideas and concepts of the Asymptotic Safety program in Quantum Einstein Gravity. Using the continuum approach based upon the effective average action, we summarize the state of the art of the field.

Book cover: From Classical To Quantum Gravity: Introduction to Loop Quantum GravityFrom Classical To Quantum Gravity: Introduction to Loop Quantum Gravity
by - arXiv ,
An introduction to the canonical quantization of gravity performed in loop quantum gravity. A special feature of this introduction is the inclusion of new proposals for coupling matter to gravity that can be used to deparametrize the theory.

Book cover: Emergent Models for Gravity: an overviewEmergent Models for Gravity: an overview
by - arXiv ,
An overview of attempts to describe gravity as an emergent phenomenon, starting from condensed matter physics to more sophisticated pregeometric models. The common line of thought is to view the graviton as a composite particle/collective moode.

Book cover: Quantum Physics, Relativity, and Complex SpacetimeQuantum Physics, Relativity, and Complex Spacetime
by - University of Massachusetts at Lowell ,
A new synthesis of the principles of quantum mechanics and Relativity is proposed in the context of complex differential geometry. The positivity of the energy implies that wave functions and fields can be extended to complex spacetime.

Book cover: Canonical Transformations in Quantum MechanicsCanonical Transformations in Quantum Mechanics
by - arXiv ,
Quantum canonical transformations are defined algebraically. This generalizes the quantum canonical transformations to include non-unitary transformations. Their importance for constructing solutions of the Schroedinger equation is discussed.

Book cover: Loop Quantum GravityLoop Quantum Gravity
by - arXiv ,
This is a (relatively) non-technical summary of the status of the quantum dynamics in Loop Quantum Gravity (LQG). We explain in detail the historical evolution of the subject and why the results obtained so far are non-trivial.

Book cover: Introduction to Modern Canonical Quantum General RelativityIntroduction to Modern Canonical Quantum General Relativity
by - arXiv ,
This is an introduction to canonical quantum general relativity, an attempt to define a mathematically rigorous, non-perturbative, background independent theory of Lorentzian quantum gravity in four spacetime dimensions in the continuum.
