Intersecting D-branes and Lifshitz-like space-time

arXiv:1204.4858 · doi:10.1103/PhysRevD.86.066009

Abstract

In a previous paper (Dey and Roy, arXiv:1203.5381) we have shown how Lifshitz-like space-times (space-times having Lifshitz scaling with hyperscaling violation) arise from 1/4 BPS, threshold F-D bound state solutions of type II string theories in the near horizon limit. In this paper we show that similar structures also arise from the near horizon limit of 1/4 BPS, threshold intersecting D-brane solutions of type II string theories. Some of these solutions are standard (D-D() for ) and some are non-standard (D-D( for ) including D2-D2, D3-D3 and D4-D4 solutions. The dilatons of these solutions in general run (except in D2-D4 and D3-D3 cases) and produce RG flows. We discuss the phase structures of these solutions. D2-D4 and D3-D3 in the near horizon limit do not produce Lifshitz-like space-time, but give AdS spaces.
