چکیده
We study the dynamical behavior of the BTZ(Banados-Teitelboim-Zanelli) black hole with the low-energy string effective action. The perturbation analysis around the BTZ black hole reveals a mixing between the dilaton and other fields. Introducing the new gauge(dilaton gauge), we disentangle this mixing completely and obtain one decoupled dilaton equation. We obtain the decay rate Γ of BTZ balck hole. It is crucial to point out that this shows the ferminonic radiation.

We introduce a set of scalar fields as test fields to study the dynamical behaviors of the BTZ(Banados-Teitelboim-Zanelli) black hole. These include minimally coupled scalar, conformally coupled scalar, and dilaton. To calculate the decay rate of the BTZ black hole, we consider both the Dirichlet boundary condition at spatial infinity and the matching procedure. It turns out that the dilaton is...

We obtain the BTZ black hole (AdS 3 ×S 3) as a non-dilatonic solution from type 0B string theory. Analyzing the perturbation around this black hole background, we show that the tachyon is not a propagating mode.

We found an infinite number of potentials surrounding 2d black hole. According to the transmission T and reflection R coefficients for scattering of string fields off 2d black hole, we can classify an infinite number of potentials into three : graviton-dilaton, tachyon and the other types. We suggest that the discrete states from all the Virasoro levels be candidates for new potentials (modes).

We study the propagation of string fields (metric Gμν , Mawxell gauge potential Aμ, dilaton Φ, and tachyon T ) in a two-dimensional (2D) charged black hole. It is shown that the tachyon is a propagating field both inside and outside the black hole. This becomes infinitely blueshifted at the inner horizon. We confirm that the inner horizon is unstable, whereas the outer horizon is stable. PACS n...
