2d Extremal Black Holes as Solitons
نویسنده
چکیده
We discuss the relationship between two-dimensional (2D) dilaton gravity models and sine-Gordon-like field theories. We show that there is a one-to-one correspondence between the solutions of 2D dilaton gravity and the solutions of a (two fields) generalization of the sine-Gordon model. In particular, we find a connection between the soliton solutions of the generalized sine-Gordon model and extremal black hole solutions of 2D dilaton gravity. As a by-product of our calculations we find a easy way to generate cosmological solutions of 2D dilaton gravity. PACS: 04.50 +h, 04.70.Bw, 11.10.Kk; E-Mail: [email protected]

Unstable two-dimensional extremal black holes
We obtain the ǫ < 2 new extremal ground states of a two-dimensional (2D) charged black hole where ǫ is the dilaton coupling parameter for the Maxwell term. The stability analysis is carried out for all these extremal black holes. It is found that the shape of potentials to an on-coming tachyon (as a spectator) take all barrier-well types. These provide the bound state solutions, which imply tha...
متن کاملOn the stability of two-dimensional extremal black holes
We discuss the stability of the extremal ground states of a two-dimensional (2D) charged black hole which carries both electric (QE) and magnetic (QM ) charges. The method is first to find the physical field and then to derive the equation of the Schrödinger type. It is found that the presenting potential to an on-coming tachyon (as a spectator) takes a barrier-well type. This provides the boun...
متن کاملBlack holes and D-branes
Black holes have an entropy proportional to the area of the horizon. The microscopic degrees of freedom that give rise to the entropy are not visible in the classical theory. String theory, a quantum theory of gravity, provides a microscopic quantum description of the thermodynamic properties of some extremal and near extremal charged black holes. The description uses properties of some string ...

We discuss the two-dimensional (2D), ǫ < 2 extremal ground states of charged black hole. Here ǫ is the dilaton coupling parameter for the Maxwell term. The complete analysis of stability is carried out for all these extremal black holes. It is found that they are all unstable. To understand this instability, we study the non-extremal charged black hole with two (inner and outer) horizons. The e...
متن کاملEntropy of extremal black holes in two dimensions.
Entropy for two dimensional extremal black holes is computed explicitly in a finite-space formulation of the black hole thermodynamics and is shown to be zero locally. Our results are in conformity with the recent one by Hawking et al in four dimensions. It is known that black holes have temperature and entropy and are therefore amenable to a thermodynamic description. For an asymptotic observe...
