Negative modes in the four–dimensional stringy wormholes
نویسنده
چکیده
We study the Giddings–Strominger wormholes in string theories. We found a non–singular wormhole solution and analyzed the perturbation around this wormhole solution. We have used the bilinear action to obtain Schrödinger– type equation for perturbation fields assuming a linear relation between the perturbation fields. With this analysis, we found an infinite number of negative modes among O(4)–symmetric fluctuations about the non–singular wormhole background.

Stringy effect of the holographic correspondence for Dp-brane backgrounds
Based on the holographic conjecture for superstrings on Dp-brane backgrounds and the dual (p + 1)-dimensional gauge theory (0 ≤ p ≤ 4) given in hep-th/0308024 and hep-th/0405203, we continue the study of superstring amplitudes including string higher modes (n 6= 0). We give a prediction to the two-point functions of operators with large Rcharge J . The effect of stringy modes do not appear as t...
متن کاملInformation Retention by Stringy Black Holes
Building upon our previous work on two-dimensional stringy black holes and its extension to spherically-symmetric four-dimensional stringy black holes, we show how the latter retain information. A key rôle is played by an infinite-dimensional W∞ symmetry that preserves the area of an isolated black-hole horizon and hence its entropy. The exactly-marginal conformal worldsheet operator representi...
متن کاملW ∞ algebras , Hawking radiation , and information retention by stringy black holes
We have argued previously, based on the analysis of two-dimensional stringy black holes, that information in stringy versions of four-dimensional Schwarzschild black holes (the singular regions of which are represented by appropriate Wess-Zumino-Witten models) is retained by quantumW symmetries when the horizon area is not preserved due to Hawking radiation. It is key that the exactly marginal ...
متن کاملOn the Stability of a Stringy Black Hole
We study the stability under perturbations of a charged four dimensional stringy black hole arising from gauging a previously studied WZW model. We find that the black hole is stable only in the extremal case Q = M . ⋆ email addresses: vaxtov::fucito and [email protected] † Permanent address: Dipartimento di Fisica, Università di Milano, 20133 Milano, Italy and INFN, Sezione di Pavia, Via Ba...
متن کامل1 J ul 2 00 9 Wormholes supported by Scalar Fields with Negative Kinetic Energy
We provide a new model of higher dimensional wormholes supported by phantom energy derived from a scalar field with negative kinetic term. We have shown that the Averaged Null Energy Condition ( ANEC ) violating phantom energy can be reduced as desired. We have also noticed that dimension of the spacetime plays a crucial role for measuring the ANEC violating matter needed.
