Abstract:

ABSTRACT:
We describe an application of the Monte Carlo method to the Janus
deformation of the black brane background. We present numerical results for
three and ve dimensional black Janus geometries with planar and spherical
interfaces. In particular, we argue that the 5D geometry with a spherical
interface has an application in understanding the nite temperature bag-like
QCD model via the AdS/CFT correspondence. The accuracy and convergence of
the algorithm are evaluated with respect to the grid spacing. The systematic
errors of the method are determined using an exact solution of 3D black
Janus. This numerical approach for solving linear problems is una ected
initial guess of a trial solution and can handle an arbitrary geometry under
various boundary conditions in the presence of source fields.
