Solution of Vacuum Field Equation Based on Physics Metrics in Finsler Geometry and Kretschmann Scalar
The Lemaître-Tolman-Bondi (LTB) model represents an inhomogeneous spherically symmetric universefilledwithfreelyfallingdustlikematterwithoutpressure. First,wehaveconsideredaFinslerian anstaz of (LTB) and have found a Finslerian exact solution of vacuum field equation. We have obtained the R(t,r) and S(t,r) with considering establish a new solution of Rµν = 0. Moreover, we attempttouseFinslergeo...
متن کاملStationary and Nonstationary Scalar Vacuum Field Noises
If stationary, the spectrum of vacuum field noise (VFN) is an important ingredient to get information about the curvature invariants of classical worldlines (relativistic classical trajectories). For scalar quantum field vacua there are six stationary cases as shown by Letaw some time ago, these are reviewed here. However, the nonstationary vacuum noises are not out of reach and can be processe...
متن کاملAsymptotic Padé-Approximant Predictions for Renormalization-Group Functions of Massive φ Scalar Field Theory
Within the context of massive N -component φ scalar field theory, we use asymptotic Padéapproximant methods to estimate from prior orders of perturbation theory the five-loop contributions to the coupling-constant β-function βg, the anomalous mass dimension γm, the vacuum-energy βfunction βv, and the anomalous dimension γ2 of the scalar field propagator. These estimates are then compared with e...
متن کاملFlavour Stability of the Chiral Vacuum and Scalar Meson Dynamics
Previous work relating the flavour variation of the chiral order parameters Fπ, 〈ūu〉 and S-wave scattering data, based on chiral sum rules and chiral perturbation theory at order p, is extended to include O(p) corrections. The finding of a significant decrease of these order parameters, particularly 〈ūu〉, with the number of flavours increasing from NF = 2 to NF = 3 is confirmed, modulo an assum...
متن کاملVacuum String Field Theory
This is a brief review of vacuum string field theory, a new approach to open string field theory based on the stable vacuum of the tachyon. We discuss the sliver state explaining its role as a projector in the space of half-string functionals. We review the construction of D-brane solutions in vacuum string field theory, both in the algebraic approach and in the more general geometrical approac...
