D-instanton and D-wormhole
نویسنده
چکیده
We study p = −1 D-brane in type IIB superstring theory. In addition to D-instanton, we obtain the D-wormhole solution in the Einstein frame. This corresponds to the ten-dimensional singular wormhole solution with infinite euclidean action.

We show that the D-instanton in the AdS5 × S5 background is a wormhole connecting the background AdS5 × S5 to the flat space R located at the position of the D-instanton. By a SL(2,R) rotation of type IIB theory, we can make the global geometry flat in string frame. We also find that, due to the tight relation between the dilaton and the axion, there is no SL(2,R) element that takes strong stri...

Instanton and wormhole solutions are constructed in a d-dimensional gravity theory with an axion-dilaton pair of scalar fields. We discuss the cases of vanishing, positive and negative cosmological constant. email: [email protected] email: [email protected]

Mobile Ad hoc Networks (MANET) are vulnerable to both active and passive attacks. The wormhole attack is one of the most severe security attacks in wireless ad hoc networks, an attack that can be mounted on a wide range of wireless network protocols without compromising any cryptographic quantity or network node. In Wormhole attacks, one malicious node tunnels packets from its location to the ...

متن کاملHolographic Schwinger effect and the geometry of entanglement.
We show that the recently proposed bulk dual of an entangled pair of a quark and an antiquark corresponds to the Lorentzian continuation of the tunneling instanton describing Schwinger pair creation in the dual field theory. This observation supports and further explains the claim by Jensen and Karch that the bulk dual of an Einstein-Podolsky-Rosen pair is a string with a wormhole on its world ...
