New Massive Gravity Domain Walls

arXiv:1008.2553 · doi:10.1016/j.physletb.2010.09.042

Abstract

The properties of the asymptotic space-times representing flat domain walls (DW's) solutions of the New Massive 3D Gravity with scalar matter are studied. Our analysis is based on order BPS-like equations involving an appropriate superpotential. The Brown-York boundary stress-tensor is used for the calculation of DW's tensions as well as of the 's central charges. The holographic renormalization group flows and the phase transitions in specific deformed dual to 3D massive gravity model with quadratic superpotential are discussed.
