What is the theory of general relativity? Understanding Einstein's ...

We proved that the Einstein field equation from general relativity is actually a relativistic quantum mechanical equation. We further modeled the universe using the equation

General Relativity as a Quantum Field Theory

A classical field theory is a physical theory that predicts how one or more fields in physics interact with matter through field equations, without considering effects of quantization; theories that

So the quantum field theory of quantum general relativity is quite normal. Indeed, general relativity is perhaps the best example of the effective field theory paradigm. It appears

QFT requires that observables in spacelike-separate regions commute with each other, but „spacelike separated“ depends on the metric, which is dynamic in GR: it depends on

It is shown there to exhibit an explicit unification of the gravitational and electromagnetic fields of force with the inertial manifestations of matter, expressing the latter explicitly in terms of a

This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical

We discuss the problems of quantum theory (QT) complicating its merging with general relativity (GR). QT is treated as a general theory of micro-phenomena—a bunch of

Allgemeine RelativitätstheorieClassical field theory

Known variously as string theory, superstring theory, and M-theory, this program (qua theory of quantum gravity) has its roots, indirectly, in the observation, dating back to at

We discuss the problems of quantum theory (QT) complicating its merging with general relativity (GR). QT is treated as a general theory of micro-phenomena—a bunch of

These notes are an introduction to General Relativity as a Quantum E ective Field Theory, following the material given in a short course on the subject at EPFL. The intent is to develop

This is a review of some of the concepts and results of the effective field theory treatment of quantum general relativity. Included are lessons of low-energy quantum gravity

Weoutline the program to apply modern quantum field theory methods to calculate observables in classical general relativity through a truncation to classical terms of the

Quantum Mechanics from General Relativity

The quantum field theoretic description of general relativity is a modern approach to gravity where gravitational force is carried by spin-2 gravitons. In the classical limit of this theory, general

In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines field theory and the principle of relativity with ideas behind quantum mechanics. [1]: xi QFT is used

General Relativity and Quantum Field Theory 1) GR makes a normal QFT 2) Emergent causality as a frontier of quantum physics 3) Quadratic gravity – the lab in the sky for causality John F.

For the last 30 years of his life, he searched for a unified field theory—a single mathematical framework that would combine gravity with electromagnetism and later, quantum

These notes are an introduction to General Relativity as a Quantum Effective Field Theory, following the material given in a short course on the subject at EPFL. The intent is to

Abstract: I describe the treatment of gravity as a quantum effective field theory. This allows a natural separation of the (known) low energy quantum effects from the (unknown)

9.2 From Classical Mechanics to Field theory 130 i)The properties of the system are compactly summarized in one function, the Lagrangian. ii)There is a direct connection between

General relativity, Einstein’s theory of gravity, is a purely classical theory that describes gravity as the warping of space-time geometry by mass and energy. But attempts to

Quantum technologies present new opportunities for fundamental tests of nature. One potential application is to probe the interplay between quantum physics and

A full quantum field theory treatment is applied. When done properly, the results encode the quantum corrections appropriate to that energy. The perturbative treatment of

the two subjects, as embodied for example in Einstein’s Theory of General Relativity or in Maxwell’s Equations for Electro-Magnetism are concerned essentially with classical fields of

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the relationship between space, time, and gravity, is in

For over a century, unified field theory has remained an open line of research. The term was coined by Albert Einstein, who attempted to unify his general theory of relativity with

View PDF Abstract: This is an introduction to the by now fifteen years old research field of canonical quantum general relativity, sometimes called „loop quantum gravity“. The

This article is meant as a summary and introduction to the ideas of effective field theory as applied to gravitational systems, ideas which provide the theoretical foundations for the modern use of

The quantum nature of gravity is an enigma which has eluded even the brightest of physicists for many decades. Now, Dr Norma G. Sanchez at the French CNRS LERMA
