Ten-dimensional supersymmetric Janus solutions Original Research Article

The reduced field equations and BPS conditions are derived in Type IIB supergravity for configurations of the Janus type, characterized by an image-slicing of image, and various degrees of internal symmetry and supersymmetry. A generalization of the Janus solution, which includes a varying axion along with a varying dilaton, and has image internal symmetry, but completely broken supersymmetry, is obtained analytically in terms of elliptic functions. A two-parameter family of solutions with 4 real supersymmetries, image internal symmetry, a varying axion along with a varying dilaton, and non-trivial image field, is derived analytically in terms of genus 3 hyper-elliptic integrals. This supersymmetric solution is the 10-dimensional Type IIB dual to the image interface super-Yang–Mills theory with image internal symmetry previously found in the literature.
