Quantization of massive scalar fields over static black string backgrounds
Abstract
The renormalized mean value of the corresponding components of the energymomentum tensor for massive scalar fields coupled to an arbitrary gravitational field configuration having cylindrical symmetry are analytically evaluated using the SchwingerDeWitt approximation, up to second order in the inverse mass value. The general results are employed to explicitly derive compact analytical expressions for the energymomentum tensor in the particular background of the blackstring spacetime. In the case of the black string considered in this work, we prove that a violation of the weak energy condition occurs at the horizon of the spacetime for values of the coupling constant, which include as particular cases the most interesting of minimal and conformal coupling.

The renormalized mean value of the quantum Lagrangian and the corresponding components of the energymomentum tensor for massive spinor fields coupled to an arbitrary gravitational field configuration having cylindrical symmetry are analytically evaluated using the SchwingerDeWitt approximation, up to second order in the inverse mass value. The general results are employed to explicitly derive compact analytical expressions for the quantum mean Lagrangian and EnergyMomentum tensor in the particular background of the blackstring spacetime.

Analytic solutions in the dyon black hole with a cosmic string: Scalar fields, Hawking radiation and energy flux
Charged massive scalar fields are considered in the gravitational and electromagnetic field produced by a dyonic black hole with a cosmic string along its axis of symmetry. Exact solutions of both angular and radial parts of the covariant Klein–Gordon equation in this background are obtained, and are given in terms of the confluent Heun functions. The role of the presence of the cosmic string in these solutions is showed up. From the radial solution, we obtain the exact wave solutions near the exterior horizon of the black hole, and discuss the Hawking radiation spectrum and the energy flux.  Highlights:more » 
Emission of massive scalar fields by a higherdimensional rotating black hole
We perform a comprehensive study of the emission of massive scalar fields by a higherdimensional, simply rotating black hole both in the bulk and on the brane. We derive approximate, analytic results as well as exact numerical ones for the absorption probability, and demonstrate that the two sets agree very well in the low and intermediateenergy regime for scalar fields with mass m{sub {Phi}{<=}1} TeV in the bulk and m{sub {Phi}{<=}0}.5 TeV on the brane. The numerical values of the absorption probability are then used to derive the Hawking radiation power emission spectra in terms of the number of extramore » 
Stressenergy tensor of quantized scalar fields in static black hole spacetimes
We present a method for the numerical computation of the stressenergy tensor of a quantized scalar field in a general static spherically symmetric spacetime, with or without horizon. The scalar field may have arbitrary curvature coupling and mass. Our method leads in a natural way to a new analytic approximation to the stressenergy tensor for massless scalar fields in these spacetimes. We use the results to compute stressenergy tensors of quantized scalar fields in Schwarzschild and ReissnerNorstrom black hole spacetimes. 
String dynamics in cosmological and black hole backgrounds: The null string expansion
We study the classical dynamics of a bosonic string in the {ital D}dimensional flat FriedmannRobertsonWalker and Schwarzschild backgrounds. We make a perturbative development in the string coordinates around a {ital null} string configuration; the background geometry is taken into account exactly. In the cosmological case we uncouple and solve the first order fluctuations; the string time evolution with the conformal gauge worldsheet {tau} coordinate is given by {ital X}{sup 0}({sigma},{tau})={ital q}({sigma}){tau}{sup 1/(1+2{beta})}+{ital c}{sup 2}{ital B}{sup 0}({sigma},{tau})+..., {ital B}{sup 0}({sigma},{tau})={summation}{sub {ital k}}{ital b}{sub {ital k}}({sigma}){tau}{sup {ital k}} where {ital q}({sigma}) is a function of the momentum component {ital P}{sub 0}({sigma}), {italmore »
