Janus solutions are constructed in d = 3, \( \mathcal{N} \) = 8 gauged supergravity. We find explicit half-BPS solutions where two scalars in the SO(1, 8)/SO(8) coset have a nontrivial profile. These solutions correspond on the CFT side to an interface with a position-dependent expectation value for a relevant operator and a source which jumps across the interface for a marginal operator.

三维N $$ \ mathcal {N} $$ = 8规格超重力的Janus解

Janus解的构造形式为d = 3，\（\ mathcal {N} \） = 8规格超重力。我们发现显式的半BPS解决方案，其中SO（1，8）/ SO（8）集合中的两个标量具有非平凡的轮廓。这些解决方案在CFT端对应于一个接口，该接口具有相关操作员的位置依赖的期望值，以及一个针对边际操作员跨越该接口的源。
