The book employs oscillatory dynamical systems to represent the Universe mathematically via constructing classical and quantum theory of damped oscillators.It further discusses isotropic and homogeneous metrics in the Friedman-Robertson-Walker Universe and shows their equivalence to non-stationary oscillators.

Le livre révèle que certaines de nos notions les plus intuitives sur le temps sont fausses et que la nature réelle du temps découverte par Einstein peut être rigoureusement expliquée sans mathématiques avancées.

Die Relativitätstheorie gehört zu den bekanntesten Theorien der Physik. Auch wenn ihre unmittelbaren Auswirkungen auf unser tägliches Leben praktisch vernachlässigbar sind, geht von ihr dennoch eine große Faszination aus. Das vorliegende Buch bahnt physikalisch interessierten Lesern mit grundlegenden Kenntnissen der höheren Mathematik einen anschaulichen und nachvollziehbaren Weg zum Verständnis der Relativitätstheorie.

Who doesn’t love a good argument? When physics heavyweights Stephen W. Hawking and Roger Penrose delivered three sets of back-and-forth lectures capped by a final debate at Cambridge’s Isaac Newton Institute, the course of modern cosmological thinking was at stake. As it happens, The Nature of Space and Time, which collects these remarks, suggests that little has changed from the days when Einstein challenged Bohr by refusing to believe that God plays dice. The math is more abstruse, the arguments more refined, but the argument still hinges on whether our physical theories should be expected to model reality or merely predict measurements.

Wilson lines (also known as gauge links or eikonal lines) can be introduced in any gauge field theory.Although the concept of the Wilson exponentials finds an enormously wide range of applications in a variety of branches of modern quantum field theory, from condensed matter and lattice simulations to quantum chromodynamics, high-energy effective.

This is the first book devoted to teleparallel Gravity (TG), an alternative theory for gravitation, which is equivalent to General Relativity (GR). Shows how TG attributes gravitation to torsion, which accounts for gravitation by acting as a force.

This book discusses the main concepts of the Standard Model of elementary particles in a compact and straightforward way.The work illustrates the unity of modern theoretical physics by combining approaches and concepts of the quantum field theory and modern condensed matter theory.

Upon treating the whole closed string massless sector as stringy graviton fields, Double Field Theory may evolve into Stringy Gravity, i.e. the stringy augmentation of General Relativity. Equipped with an O(D,D) covariant differential geometry beyond Riemann, we spell out the definition of the energy–momentum tensor in Stringy Gravity and derive its on-shell conservation law from doubled general covariance. Equating it with the recently identified stringy Einstein curvature tensor, all the equations of motion of the closed string massless sector are unified into a single expression, GAB=8πGTAB, which we dub the Einstein Double Field Equations. As an example, we study the most general D=4 static, asymptotically flat, spherically symmetric, ‘regular’ solution, sourced by the stringy energy–momentum tensor which is nontrivial only up to a finite radius from the center. Outside this radius, the solution matches the known vacuum geometry which has four constant parameters. We express these as volume integrals of the interior stringy energy–momentum tensor and discuss relevant energy conditions.

The purpose of this book is to give a systematic pedagogical exposition of the quantitative analysis of Wilson lines and gauge-invariant correlation functions in quantum chromodynamics. Using techniques from the previous volume (Wilson Lines in Quantum Field Theory, 2014), an ab initio methodology is developed and practical tools for its implementation are presented. Emphasis is put on the implications of gauge invariance and path-dependence properties of transverse-momentum dependent parton density functions. The latter are associated with the QCD factorization approach to semi-inclusive hadronic processes, studied at currently operating and planned experimental facilities.
