AdS/BCFT correspondence and Lovelock theory in the presence of canonical scalar field

Abstract

In the current study, authors present the comprehensive analysis of the Anti-de Sitter/Boundary Conformal Field Theory (AdS/BCFT) correspondence for Lovelock theory of second order in the presence of canonical (and real) scalar field non-minimally coupled to modified gravitation sector. Authors consider the special case with three dimensional BTZ (Banados-Teitelboim-Zanelli) black hole and dual 2D Conformal Field Theory with the additional boundary for higher dimensional AdS spacetime. Moreover, for the given case additional boundary profile was investigated, as well as the holographic renormalization procedure for Lovelock-scalar theory. Besides, from holographic renormalization black hole entropy was obtained numerically. Finally, from the entropy and black hole temperature dual to BCFT some thermodynamical quantities, such as heat capacity, sound speed, energy-momentum trace and Hawking-Page phase transition were probed.
