Abstract We give a large class of supersymmetric Janus solutions in $$\omega $$ ω -deformed (dyonic) SO(8) maximal gauged supergravity with $$\omega =\frac{\pi }{8}$$ ω = π 8 . Unlike the purely electric counterpart, the dyonic SO(8) gauged supergravity exhibits a richer structure of $$AdS_4$$ A d S 4 vacua with $$N=8,2,1,1$$ N = 8 , 2 , 1 , 1 supersymmetries and SO(8), U(3), $$G_2$$ 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 $$AdS_3$$ A d S 3 -sliced domain walls asymptotically interpolating between the aforementioned $$AdS_4$$ 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 $$AdS_4$$ A d S 4 vacua. We also give a class of solutions interpolating among the SO(8), $$G_2$$ G 2 and U(3) $$AdS_4$$ A d S 4 vacua in the case of $$\omega =0$$ ω = 0 which have not previously appeared in the presently known Janus solutions of electric SO(8) gauged supergravity.
