Query: Holographic RG flows and Janus solutions from matter-coupled N=4 gauged
  supergravity   We study an $SO(2)\times SO(2)\times SO(2)\times SO(2)$ truncation of
four-dimensional $N=4$ gauged supergravity coupled to six vector multiplets
with $SO(4)\times SO(4)$ gauge group and find a new class of holographic RG
flows and supersymmetric Janus solutions. In this truncation, there is a unique
$N=4$ supersymmetric $AdS_4$ vacuum dual to an $N=4$ SCFT in three dimensions.
In the presence of the axion, the RG flows generally preserve $N=2$
supersymmetry while the supersymmetry is enhanced to $N=4$ for vanishing axion.
We find solutions interpolating between the $AdS_4$ vacuum and singular
geometries with different residual symmetries. We also show that all the
singularities are physically acceptable within the framework of
four-dimensional gauged supergravity. Accordingly, the solutions are
holographically dual to RG flows from the $N=4$ SCFT to a number of
non-conformal phases in the IR. We also find $N=4$ and $N=2$ Janus solutions
with $SO(4)\times SO(4)$ and $SO(2)\times SO(2)\times SO(3)\times SO(2)$
symmetries, respectively. The former is obtained from a truncation of all
scalars from vector multiplets and can be regarded as a solution of pure $N=4$
gauged supergravity. On the other hand, the latter is a genuine solution of the
full matter-coupled theory. These solutions describe conformal interfaces in
the $N=4$ SCFT with $N=(4,0)$ and $N=(2,0)$ supersymmetries.
