| Summary: | In this paper, we perform a systematic analysis of tachyon condensation over string Newton-Cartan (NC) geometry by probing the background with non BPS Dp brane. We construct the finite tachyon effective action for NC geometry and explore the dynamics associated with the tachyon kink on the world-volume of the non BPS Dp brane. We show that under certain specific assumptions, the spatial dependent tachyon condensation leads to an emerging BPS D(p−1) brane dynamics over NC background. We further compute the stress energy tensor and show the equivalence between two different Dp brane configurations in the NC limit. |
