Perturbative calculation of quasi-normal modes
نویسنده
چکیده
I discuss a systematic method of analytically calculating the asymptotic form of quasi-normal frequencies. In the case of a four-dimensional Schwarzschild black hole, I expand around the zeroth-order approximation to the wave equation proposed by Motl and Neitzke. In the case of a five-dimensional AdS black hole, I discuss a perturbative solution of the Heun equation. The analytical results are in agreement with the results from numerical analysis.

New Results on Perturbative Color Transparency in Quasi-Exclusive Electroproduction
We review the perturbative QCD formalism of hadronic electromagnetic form factors and the color transparency ratio for quasi-exclusive electroproduction of the proton and pion from nuclear targets. We have completed the first full calculations including all leading order quark subprocesses and integrations over distribution amplitudes, including Sudakov effects. For the case of the proton, the ...
متن کاملRoundtrip matrix method for calculating the leaky resonant modes of open nanophotonic structures.
We present a numerical method for calculating quasi-normal modes of open nanophotonic structures. The method is based on scattering matrices and a unity eigenvalue of the roundtrip matrix of an internal cavity, and we develop it in detail with electromagnetic fields expanded on Bloch modes of periodic structures. This procedure is simpler to implement numerically and more intuitive than previou...
متن کاملSynchronizing an array of quasi-harmonic oscillators
We present a general approach to the study of synchrony in networks of weakly nonlinear, quasi-harmonic oscillators, described by equations of the type x′′ + x + f(x, x′) = 0. By performing a perturbative calculation based on normal form theory we analytically obtain an O( ) approximation to the eigenvalues that determine the stability of the synchronous, inphase solution. All steps are justifi...
متن کاملExclusive central production of dijets at hadronic colliders
We critically re-examine the calculation of central production of dijets in quasi-elastic hadronic collisions. We find that the process is not dominated by the perturbative contribution, and discuss several sources of uncertainties in the calculation.
متن کاملLarge mass expansion of quasi-normal modes in AdS5
We calculate analytically the asymptotic form of quasi-normal frequencies for massive scalar perturbations of large black holes in AdS5. We solve the wave equation, which reduces to a Heun equation, perturbatively and calculate the wave function as an expansion in 1/m, where m is the mass of the mode. The zeroth-order results agree with expressions derived by numerical analysis. We also calcula...
