Book Synopsis A First Course in Loop Quantum Gravity by : Rodolfo Gambini
Download or read book A First Course in Loop Quantum Gravity written by Rodolfo Gambini and published by OUP Oxford. This book was released on 2011-09-22 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an accessible introduction to loop quantum gravity and some of its applications, at a level suitable for undergraduate students and others with only a minimal knowledge of college level physics. In particular it is not assumed that the reader is familiar with general relativity and only minimally familiar with quantum mechanics and Hamiltonian mechanics. Most chapters end with problems that elaborate on the text, and aid learning. Applications such as loop quantum cosmology, black hole entropy and spin foams are briefly covered. The text is ideally suited for an undergraduate course in the senior year of a physics major. It can also be used to introduce undergraduates to general relativity and quantum field theory as part of a 'special topics' type of course.
Download or read book Quantum Space written by Jim Baggott and published by Oxford University Press. This book was released on 2018-11-08 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes ": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.

Download or read book Quantum Gravity written by Carlo Rovelli and published by Cambridge University Press. This book was released on 2007-11-29 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this 2004 book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian physics required by general relativity. The second part covers the basic technical research directions. Appendices include a detailed history of the subject of quantum gravity, hard-to-find mathematical material, and a discussion of some philosophical issues raised by the subject. This fascinating text is ideal for graduate students entering the field, as well as researchers already working in quantum gravity. It will also appeal to philosophers and other scholars interested in the nature of space and time.

Book Synopsis Loop Quantum Gravity by : Paul F. Kisak
Download or read book Loop Quantum Gravity written by Paul F. Kisak and published by Createspace Independent Publishing Platform. This book was released on 2016-10-09 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loop quantum gravity (LQG) had its origins with theories based on the quantum geometries of space-time. Theoretical physics has been working towards developing a theory of everything (TOE) for decades. The spirit of the effort appears to have a basis in fact as experimental evidence from The Large Hadron Collider and The Hubble Telescope continue to provide pieces of information that both confirm theories (Higgs Boson) and continue to raise new and confounding issues such as Dark Matter and Dark Energy. LQG is a remarkable attempt to incorporate the math of quantum mechanics and Einstein's theory of general relativity. A major focus is on developing the math of the geometric "granularity" or quantization of space. The fundamental concept behind LQG is that space is mathematically modeled as a very fine interconnected network of finite loops. These 'loops' form structures on the order of a Planck Length which is approximately 10 DEGREES DEGREES-35 meters. There are basically two variations being explored in LQG with one being canonical loop quantum gravity and a more recent variant known as covariant loop quantum gravity or 'spin-foam' theory. LQG is also being applied to the field of cosmology and is termed Loop Quantum Cosmology (LQC). This book is designed to be a reference and provide an overview of the topic and give the reader a structured knowledge to familiarize yourself with the topic at the most affordable price possible. The accuracy and knowledge is of an international viewpoint as the edited articles represent the inputs of many knowledgeable individuals and some of the most current knowledge on the topic, based on the date of publication.

Book Synopsis The Relationship Between Cues from Loop Quantum Gravity and Superradiation by : Wen -. Xiang Chen
Download or read book The Relationship Between Cues from Loop Quantum Gravity and Superradiation written by Wen -. Xiang Chen and published by Eliva Press. This book was released on 2021-10-07 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loop quantum gravity theory, the English alias loop gravity, quantum geometry; the quantum gravity theory developed by Abbe Ashitika, Lee Smalling, Carlo Rowley, etc., is the same as string theory It is the most successful theory of quantizing gravity today.The theory of using the perturbation theory of quantum field theory to realize the quantization of the theory of gravity cannot be renormalized. If you start with general relativity while advocating that space-time has only four dimensions, you can turn general relativity into a theory similar to gauge field theory. The basic regular variable is the Ashitika-Barbero connection instead of the metric tensor, and then the connection is defined The translation operator and the flux variable are the basic variables to achieve quantization.This book points out that when some boundary conditions are preset, bosons can produce Bose condensation without an energy layer. Under Bose condensation, the incident wave may be condensed in various black holes in the theory of loop quantum gravity. At that time, potential barriers can be generated near the event horizon of various black holes, and we believe that those black holes will also produce superradiation phenomena (this article adopts the natural unit system). We assume that the simple theoretical model of loop quantum gravity, which can produce super-radiation phenomena that do not exist in traditional theory, provides experimental evidence of loop quantum gravity.

Book Synopsis Once Before Time by : Martin Bojowald
Download or read book Once Before Time written by Martin Bojowald and published by Vintage. This book was released on 2011-11-01 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his introduction to a revolutionary theory of the cosmos, Martin Bojowald shows how the big bang theory may give way to the big bounce theory, which describes our universe as an eternal series of expansions and contractions, with no beginning and no end. In 2000, Bojowald, then a twenty-seven-year-old postdoctoral student at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology, or LQC, was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.
