Title: Quantization of massive scalar fields over static black string backgrounds

Abstract

The renormalized mean value of the corresponding components of the energy-momentum tensor for massive scalar fields coupled to an arbitrary gravitational field configuration having cylindrical symmetry are analytically evaluated using the Schwinger-DeWitt approximation, up to second order in the inverse mass value. The general results are employed to explicitly derive compact analytical expressions for the energy-momentum tensor in the particular background of the black-string space-time. 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 space-time 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 energy-momentum tensor for massive spinor fields coupled to an arbitrary gravitational field configuration having cylindrical symmetry are analytically evaluated using the Schwinger-DeWitt 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 Energy-Momentum tensor in the particular background of the black-string spacetime.
  • 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 » •A cosmic string is introduced along the axis of symmetry of the dyonic black hole. •The covariant Klein–Gordon equation for a charged massive scalar field in this background is analyzed. •Both angular and radial parts are transformed to a confluent Heun equation. •The resulting Hawking radiation spectrum and the energy flux are obtained.« less
  • We perform a comprehensive study of the emission of massive scalar fields by a higher-dimensional, 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 intermediate-energy 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 » dimensions, angular-momentum of the black hole and mass of the emitted field. We compute the total emissivities in the bulk and on the brane, and demonstrate that, although the brane channel remains the dominant one, the bulk-over-brane energy ratio is considerably increased (up to 34%) when the mass of the emitted field is taken into account.« less
  • We present a method for the numerical computation of the stress-energy 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 stress-energy tensor for massless scalar fields in these spacetimes. We use the results to compute stress-energy tensors of quantized scalar fields in Schwarzschild and Reissner-Norstrom black hole spacetimes.
  • We study the classical dynamics of a bosonic string in the {ital D}-dimensional flat Friedmann-Robertson-Walker 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 world-sheet {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 » b}{sub {ital k}}({sigma}) are obtained from the equation for the first order fluctuations, and {beta} is the exponent of the conformal factor in the Friedmann-Robertson-Walker metric, i.e., {ital R}{approx}{eta}{sup {beta}}. The string proper size, at first order in the fluctuations, grows such as the conformal factor {ital R}({eta}) and the string energy-momentum tensor corresponds to that of a null fluid. For a string in the black hole background, we study the planar case, but keep the dimensionality of the spacetime {ital D} generic. In the null string expansion, the radial, azimuthal, and time coordinates ({ital r},{phi},{ital t}) are {ital r}={summation}{sub {ital nA}}{sup 1}{sub {ital n}}({sigma})({minus}{tau}){sup 2{ital n}/({ital D}+1)}, {phi}={summation}{sub {ital n}}{ital A}{sup 3}{sub {ital n}}({sigma})(-{tau}){sup ({ital D}-5+2{ital n})/({ital D}+1)}, and {ital t}={summation}{sub {ital n}}{ital A}{sup 0}{sub {ital n}}({sigma})(-{tau}){sup 1+2{ital n}({ital D}-3)/({ital D}+1)}. The first terms of the series represent a {ital generic} approach to the Schwarzschild singularity at {ital r}=0. First and higher order string perturbations contribute with higher powers of {tau}.« less
