We give a large class of supersymmetric Janus solutions in ω -deformed (dyonic) SO (8) maximal gauged supergravity with ω = π 8 . Unlike the purely electric counterpart, the dyonic SO (8) gauged supergravity exhibits a richer structure of A d S 4 vacua with N = 8 , 2 , 1 , 1 supersymmetries and SO (8), U (3), G 2 and SU (3) symmetries, respectively. Similarly, domain walls interpolating among these critical points show a very rich structure as well. In this paper, we show that this gauged supergravity also accommodates a number of interesting supersymmetric Janus solutions in the form of A d S 3 -sliced domain walls asymptotically interpolating between the aforementioned A d S 4 geometries. These solutions could be holographically interpreted as two-dimensional conformal defects within the superconformal field theories (SCFTs) of ABJM type dual to the A d S 4 vacua. We also give a class of solutions interpolating among the SO (8), G 2 and U (3) A d S 4 vacua in the case of ω = 0 which have not previously appeared in the presently known Janus solutions of electric SO (8) gauged supergravity.
