Hardcover. Etat : new. Hardcover. Quantum gravity is at the frontier of research in physics. The four known interactions - gravitational, electromagnetic, strong and weak nuclear forces - have successfully described all known phenomena, with the exception of the dark sector. Of the four, the quantum of gravitational interaction is yet to be discovered, due to the weakness of the interaction at small scales. However, gravitational interaction is very strong for astrophysical objects, and bizarre phenomena have been tested experimentally. Using general relativity, gravity is shown as the theory of space-time, and theoretical predictions of black holes, and gravitational lensing, have all been observed in astrophysics. Gravitational waves, recently discovered, brings forth new hope for observational gravitational physics in the realm of the infinitesimal, to the point that the physics of quantum gravity may be within reach. The two volumes of the Universe Special Issue on quantum gravity phenomenology are therefore very timely, with papers describing the search for quantum signatures of gravity in observational physics. Due to the difficulty or impossibility of direct experiments, One of the avenues explored is analog models of gravity. Curved graphene was used to simulate the geometry of the outside of a black hole, and supersonic matter waves could simulate horizon behavior in fluids. Volume I of the Special Issue focuses on these "simulated quantum gravity experiments" or analog models with papers by pioneers in the field. Volume II describes quantum effects in astrophysical and cosmological phenomena which provide predictions for future experiments. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.

Taschenbuch. Etat : Neu. Neuware -The practical implementation of general symmetry principles in the context of effective theories or, more generally, theories with a non-standard phase-space and unusual Lagrangians is often a difficult task that leads to new insights. In this work we deal with an important supersymmetric model the N=2 pure Yang-Mills effective gauge theory -- a four-dimensional non-trivial fully integrable quantum field theory, as shown by Seiberg and Witten -- and construct its supersymmetry currents. The study was carried on with a precise goal in mind that is the computation of the central charge of the model that is the ''''meeting point'''' of all types of charges and symmetries present in the theory: supersymmetry, gauge (spontaneously broken) symmetry, topological charges and (discrete) electro-magnetic duality symmetry. The richness of the model, the vast areas of application of the method employed (Noether theorem) and the explicit and careful explanation of every detail, make many aspects of the results reported here directly or indirectly applicable to disparate areas of the theoretical investigation of symmetries.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.
