In this paper, we consider a quantum scalar field propagating on the Reissner-Nordstrom black hole spacetime. We compute the renormalized stress-energy tensor for the field in the Hartle-Hawking, Boulware and Unruh states. When the field is in the Hartle-Hawking state, we renormalize using the...
Vacuum stressenergy tensor of nonconformal scalar field in quasi-Euclidean gravitational background - Bordag, Lindig, et al. - 1997 () Citation Context ... in inflationary models [4], the condition ξ = 0 is usually assumed. In investigations of quantum effects in a curved space-time, ...
Again the quantity is a scalar field, i.e., the energy density as measured in the rest frame of the medium. Jul 21, 2022 #8 martinbn Science Advisor 3,846 1,979 pervect said: I'm not sure what the author is trying to say. Consider a stress energy tensor of a continuum ...
We show that the set of ambiguities in the renormalized expected stress-energy tensor allowed by the Wald axioms is much larger for a massive scalar field (an infinite number of free parameters) than for a massless scalar field (two free parameters). We also use the closed-time-path effecti...
The stress-energy tensor of a massless scalar field is calculated for a 'general' two-dimensional black hole. The black hole is found always to emit blackb... Hiscock,A William - 《Physical Review D Particles & Fields》 被引量: 11发表: 1977年 Stress-energy tensor of an electromagnetic ...
field theory. Themain object of researches in the field is the stress-energy-momentum tensor (SEMT), whichis a source of gravity in Einstein’s field equation. Vacuum expectation value of the SEMTgives a way to describe effects of quantum field on the space-time geometry in the frameworkof...
In this paper, we generalize the deformations driven by the stress-energy tensor $T$ and investigate their relation to the flow equation for the background metric at the classical level. For a deformation operator $\mathcal O$ as a polynomial function of the stress-energy tensor, we develop...

In this paper we will investigate whether this drawback can be overcome by replacing the Hamiltonian operatorHby an average of a suitable component of the quantum stress tensor, essentially an averaged energy density. For definiteness we will consider a massive minimally coupled free scalar field, ...
My post https://www.physicsforums.com/threa...tional-field-wei-tou-ni-stress-energy.969033/ got no replies. So I formulated those statements on the stress-energy tensor (SET) which are of most interest to me. I would be very grateful if you either confirmed them or explained when and ...
