The Klein–Gordon equation ( Klein–Fock–Gordon equation or sometimes Klein–Gordon–Fock equation ) is a relativistic wave equation, related to the Schrödinger equation. If e 0 ∈ R 1+1 is a future-directed timelike unit vector, and if e 1 is the unique spacelike unit vector with e 0 e 1 = 0 that “points to the right,” then coordinates x 0 and x 1 on R 1+1 are defined by x 0 (q) := qe 0 and x 1 (q) := qe 1. These two equations together are known as the Einstein-Klein-Gordon system.

A novel approach to the synthesis of nondispersive wave packet solutions to the Klein-Gordon and Dirac equations Amr M. 2 Maxwell's equations 156 5. How to use the einstein energy-momentum relation to derive the Klein Gordon Wave Equation. org 85 | Page 2 1 20 ) 2 2 1( ec mm )21()1( 20 ec m Thus )1( 2 1 2 2 0 22 e ee c cmcmcm 00 mm )22(0 Vm Since atomic particles which are describes by quantum laws are very small, thus one can neglect 0m. Attractors of the Einstein-Klein-Gordon System A key question in general relativity is whether solutions to the Einstein equations, viewed as an initial value problem, are stable to small perturbations of the initial data. Derivation of Schrodinger and Einstein Energy equations from Maxwell's electric wave Equation DOI: 10. varying "wave. Breakdown Criteria Arick Shao Introduction The Breakdown Problem Some Classical Results The Einstein Vacuum Equations The Main Results Nonvacuum Spacetimes The Main Theorem The Cauchy Problem Energy Estimates Generalized EMT’s Global Energy Estimates Local Energy Estimates Representation Formulas Preliminaries Applying the Parametrix The. Hello Friend The answer of u r question is. It provides an accurate calculation of the. 3 Schr odinger form of the Klein Gordon Equation In addition to expressing the Klein-Gordon equation in terms of a partial di erential equation that is rst order in space and time (which by default introduces Spinors) it is also possible to express the Klein-Gordon equation as a set of coupled Schr odinger type equations thus (using natural. Beyera Center for Computation and Technology (CCT), Louisiana State University (LSU), 328 Johnston Hall, Louisiana 70803, USA and Max Planck Institute for Gravitational Physics, Albert Einstein Institute (AEI), Am Mühlenberg 1, D-14476 Potsdam, Germany. In this paper, we consider the problem of the existence and uniqueness of solutions to the Einstein field equations for a spatially flat Friedmann-Lemaître-Robertson-Walker universe in the context of stochastic eternal inflation, where the stochastic mechanism is modelled by adding a stochastic forcing term representing Gaussian white noise to the Klein-Gordon equation. As a consequence, we also arrive at a purely operator theoretic proof of the well-posedness of the initial value problem of the reduced normalized Klein-Gordon equation in the grav-itational field of a Kerr black hole in the weighted L2-space. English Turkish online dictionary Tureng, translate words and terms with different pronunciation options. He then derives the action, Lagrangian, and equations of motion for this case, and shows that the equations of motion are wave equations with a singularity at the location of the particle. We prove the non- linear future stability, and show that the perturbed spacetimes are future causally geodesically complete. Classical and Quantum Gravity PAPER The Klein Gordon equation on the toric AdS-Schwarzschild black hole To cite this article: Jake Dunn and Claude Warnick 2016 Class. In the non-relativistic limit the Klein-Gordon equation reduces to the quintic non-linear Schrödinger equation. Separability of the Klein-Gordon equation 5 5. We rewrite the complex Klein-Gordon (KG) equation with a mexican-hat scalar field potential in a thermal bath with one loop contribution as a new Gross-Pitaevskii-like equation. We examine the Einstein equation coupled to the Klein-Gordon equation for a complex-valued scalar eld. The equation of motion of a scalar field, also known as the Klein Gordon equation, is given by d 2 φ/dt 2 + 3Hdφ/dt + dV(φ)/dφ = 0, which has the exact same form as a damped harmonic oscillator, 3Hdφ/dt being the “Hubble friction” term caused by the expansion of the universe. By considering a random walk model compounded in Einstein's evolution equation, we show that both the classical Schrodinger and Klein-Gordon equations can be viewed a s consequence of introducing a memory function. Assuming that the geometry is a solution to the Einstein equations Gμν =−8πTμν, (2) the Raychaudhuri equation (1) becomes ∇Uθ =−8πρ −2σ2 − θ2 n −1, (3) where ρ = TμνUμUν − T n −2 (4) and T = Tμμ. We study the propagation of waves across fixed mesh refinement boundaries in linear and nonlinear model equations in 1-D and 2-D, and in the 3-D Einstein equations of general relativity. Unstable mode solutions to the Klein-Gordon equation in Kerr. One is the Klein-Gordon equation with power nonlinearity: with the constant or , and another is the nonlinear Schrödinger equation: with a trapping potential and. Swedish University dissertations (essays) about LINEAR KLEIN-GORDON EQUATION. 14, it was shown that the Klein– Gordon equation with a self-interacting scalar field in a thermal bath, reduces to. Evolution Equations in the Einstein & de Sitter spacetime, Faculty Travel Support Program, $800. mx: Tienda Kindle. We construct unique local solutions for the spherically-symmetric Einstein-Klein-Gordon-anti-de Sitter (AdS) system subject to a large class of initial and boundary conditions including some consid. Quantum mechanics: Derive Schrödinger, Klein-Gordon and Dirac equations 3 of 3 A new explanation is provided that is based on doing Newtonian calculus correctly in Einstein's spacetime via. Shaarawi and loannis M. The idea of Dirac was to demand that there be Hamiltonian that is linear in such the square of would give the required formula. We consider the second quantization procedure for a KLEIN GORDON equation with time dependent Hamiltonian and with replaced second order time derivative by the appropriate difference operator. Klein and Gordon instead worked with the square of this equation (the Klein-Gordon equation for a free particle), which in covariant notation reads The Klein-Gordon equation was actually first found by Schrödinger, before he made the discovery of the equation that now bears his name. A new email fraud scheme has taken Business Email Compromise (BEC) to a whole new level of sophistication. 1, 289-345]. It is a quantum relativistic wave equation, used in the description of particles with spin 0. Posts about Klein-Gordon equation written by AltExploit.
