Modifications of the BTZ black hole by a dilaton and scalar

We investigate some modifications of the static BTZ black hole solution due to a chosen asymptotically constant dilaton and scalar. New classes of static black hole solutions are obtained. One of the solutions contains the Martinez-Zanelli conformal black hole solution as a special case. Using the quasilocal formalism, we calculate their mass for a finite spatial region that contains the black hole. Their temperatures are also computed. Finally, using some of the curvature singularities as examples, we investigate whether or not a quantum particle behaves singularly.
