Quantum-corrected three-dimensional AdS space-time

We study quantum-corrected solitons in global, three-dimensional, anti-de Sitter (AdS) space-time. These static solitons have a regular origin and arise as solutions of the linearized quantum-corrected Einstein equations (LQCEE). On the right-hand-side of the LQCEE is the renormalized expectation value of the stress-energy tensor operator for a massless, conformally coupled, quantum scalar field in a nonrotating thermal state, computed in quantum field theory (QFT), or using relativistic kinetic theory (RKT). We calculate the mass of the solitons and compare the results from QFT and RKT.
