摘要

We construct holographic Janus solutions,which describe a conformal interface in the theory of M2-branes,in four-dimensional gauged supergravities using a perturbative method.In particular,we study three Einsteinscalar systems and their BPS equations,which are derived by Bobev,Pilch,and Warner (2014).The actions of our interest are all consistent truncations of D=11 supergravity,chosen to be invariant under SO(4)×SO(4),S U(3)× U(1)× U(1),and G2 symmetry subgroups of S O(8).The utility of our semi-analytic result is illustrated by the calculation of minimal area surface and the associated holographic entanglement entropy.
