Heat kernel and scaling of gravitational constants.

چکیده
We consider the non-local energy-momentum tensor of quantum scalar and spinor fields in 2w-dimensional curved spaces. Working to lowest order in the curvature we show that, while the non-local terms proportional to 2R, 22R, . . . ,2w−2R are fully determined by the early-time behaviour of the heat kernel, the terms proportional to R depend on the asymptotic latetime behaviour. This fact explains a discrepancy between the running of the Newton constant dictated by the RG equations and the quantum corrections to the Newtonian potential.

Compressed Liquid Densities for Binary Mixtures at Temperatures from 280- 440K at Pressures up to 200 MPa
A method for predicting liquid densities of binary mixtures from heat of vaporization and liquid densityat boiling point temperature (ΔHvap and n b ρ ) as scaling constants, is presented. B2(T) follows a promisingcorresponding-states principle. Calculation of α(T) and b(T), the two other temperature-dependentconstants of the equation of state, are made possible by scaling. As a result ΔHvap and...
متن کاملCFD Investigation of Gravitational Sedimentation Effect on Heat Transfer of a Nano-Ferrofluid
In the present attempt, flow behavior and thermal convection of one type of nanofluids in a disc geometry was investigated using Computational Fluid Dynamics (CFD). Influence of gravity induced sedimentation also has been studied. The commercial software, Fluent 6.2, has been employed to solve the governing equations. A user defined function was added to apply a uniform external ma...
متن کاملA ug 2 00 6 Random walk on graphs with regular resistance and volume growth ∗
In this paper characterizations of graphs satisfying heat kernel estimates for a wide class of space-time scaling functions are given. The equivalence of the two-sided heat kernel estimate and the parabolic Harnack inequality is also shown via the equivalence of the upper (lower) heat kernel estimate to the parabolic mean value (and super mean value) inequality.
متن کاملAn Analytical Equation of State for Saturated Liquid Refrigerant Ternary Mixtures
In this work an analytical equation of state has been employed to calculate the PVT properties ofternary refrigerant mixtures. The theoretical EoS is that of Ihm, Song and Mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization ΔHvapand molar density ρnb, both at the normal boiling temperature. The following three temperaturedepende...
متن کاملThe scaling evolution of the cosmological constant
In quantum field theory the parameters of the vacuum action are subject to renormalization group running. In particular, the “cosmological constant” is not a constant in a quantum field theory context, still less should be zero. In this paper we continue with previous work, and derive the particle contributions to the running of the cosmological and gravitational constants in the framework of t...
