Deformations of the AlmheiriPolchinski model
Abstract
We study deformations of the AlmheiriPolchinski (AP) model by employing the YangBaxter deformation technique. The general deformed AdS_{2} metric becomes a solution of a deformed AP model. In particular, the dilaton potential is deformed from a simple quadratic form to a hyperbolic functiontype potential similarly to integrable deformations. A specific solution is a deformed black hole solution. Because the deformation makes the spacetime structure around the boundary change drastically and a new naked singularity appears, the holographic interpretation is far from trivial. The Hawking temperature is the same as the undeformed case but the BekensteinHawking entropy is modified due to the deformation. This entropy can also be reproduced by evaluating the renormalized stress tensor with an appropriate counterterm on the regularized screen close to the singularity.
