Since we now have a Time itself is being extended outward in a unidirectional direction, but due to the electromagnetic nature of quantum particles, our space per time or Space / Time is being curved. This has been extended further by taking into account polynomials of the scalar curvature (R) (so-called (f(R))-truncations) (Codello et. If gravity is the curvature of space-time then how can it ever be described by a quantum theory. The second input is to take some spacetime manifold (like flat Minkowski space or something more curved) and attach a C*-algebra to each open subset in a compatible way. The Skyrmion as a fermi field enters the picture when this potential energy portion has Bogoliubov coefficients, which both define quantum field in curved spacetime and superconductivity. This Amrita talk was the only presentation from “Around sufficiently small particles space-time can be substantially curved giving rise to time dilation and space contraction effects as with particles moving at high velocities. As a postdoctoral fellow at Cambridge University, he worked with Stephen Hawking in cosmology, quantum field theory in curved space time and quantum theories of gravitation. Topics discussed here include: a comparison with Euclidean quantum field theory, supersymmetry and general relativity. Boundary divergences in vacuum self-energies and quantum field theory in curved spacetime. References · Citing Articles (3). Shanti's paper was titled Relativity of Scale: Emergence of Quantum Behavior from Space-Time Geometry and Its Implications. Its physics-related activities extend to the fields of academia, research and outreach. Al., 2009), and the square of the Weyl curvature tensor (Benedetti et. Quantum Einstein Gravity (QEG) is the generic name for any quantum field theory of gravity that (regardless of its bare action) takes the spacetime metric as the dynamical field variable and whose symmetry is given by diffeomorphism invariance. Since it has surrounding curved strings representing an electromagnetic field ( because quantum particle masses are measured in electron volts ) we can let this electromagnetic field be represented by 5 ( add the digits in 23 ( 2 + 3 = 5 ). As explained in the discussion of the stress-energy curvature in the previous post, in addition to the gravity mediators (gravitons) presumably being quantized rather than a continuous or continuum curved spacetime, there is the Quantum field theory is suggestive that the correct Feynman diagram for any interaction is not a continuous, smooth curve, but instead a number of steps due to discrete interactions of the field quanta with the charge (i.e., gravitational mass). If it is a graviton field then it is not the curvature of space-time but the interaction of the graviton force particles. Download: PDF (157 kB) Buy this article Export: BibTeX or EndNote (RIS).
