Pt −symetrically Regularized Eckart, Pöschl-teller and Hulthén Potentials
PT (= parity times time-reversal) symmetry of complex Hamiltonians with real spectra is usually interpreted as a weaker mathematical substitute for Hermiticity. Perhaps an equally important role is played by the related strengthened analyticity assumptions. In a constructive illustration we complexify a few potentials solvable only in s−wave. Then we continue their domain from semi-axis to the ...
متن کاملAsymptotic Quasinormal Frequencies of d-dimensional Schwarzschild Black Holes
We determine the quasinormal frequencies for all gravitational perturbations of the ddimensional Schwarzschild black hole, in the infinite damping limit. Using the potentials for gravitational perturbations derived recently by Ishibashi and Kodama, we show that in all cases the asymptotic real part of the frequency is proportional to the Hawking temperature with a coefficient of log 3. Via the ...
متن کاملAsymptotic Quasinormal Frequencies of Brane-Localized Black Hole
The asymptotic quasinormal frequencies of the brane-localized (4 + n)dimensional black hole are computed. Since the induced metric on the brane is not an exact vacuum solution of the Einstein equation defined on the brane, the real parts of the quasinormal frequencies ω do not approach to the wellknown value TH ln 3 but approach to TH ln kn, where kn is a number dependent on the extra dimension...

15 صفحه اولOn the Classification of Asymptotic Quasinormal Frequencies for d–Dimensional Black Holes and Quantum Gravity
We provide a complete classification of asymptotic quasinormal frequencies for static, spherically symmetric black hole spacetimes in d dimensions. This includes all possible types of gravitational perturbations (tensor, vector and scalar type) as described by the Ishibashi–Kodama master equations. The frequencies for Schwarzschild are dimension independent, while for Reissner–Nordstrøm are dim...
