Induced gravity (or emergent gravity) is an idea in quantum gravity that spacetime curvature and its dynamics emerge as a mean field approximation of underlying microscopic degrees of freedom, similar to the fluid mechanics approximation of Bose–Einstein condensates. The concept was originally … Meer weergeven Sakharov observed that many condensed matter systems give rise to emergent phenomena that are analogous to general relativity. For example, crystal defects can look like curvature and torsion in an Some argue … Meer weergeven • Black hole thermodynamics • Entropic force • List of quantum gravity researchers Meer weergeven • Carlos Barcelo, Stefano Liberati, Matt Visser, Living Rev.Rel. 8:12, 2005. • D. Berenstein, Emergent Gravity from CFT, online lecture. Meer weergeven WebInduced gravity[17] is similarto standardscalar-tensor theories, but gravity is induced by a Higgs-like field. One motivation stems from Einstein’s original ideas to incor-porate …

WebWe discuss the B modes induced by gravitational lensing and by Galactic foregrounds and show how both are distinguished from those induced by inflationary gravitational waves. Issues involved in the experimental pursuit of these B modes are described, and we summarize some of the strategies being pursued. WebThus the rate of change of the magnetic flux is.
