A note on interface solutions in higher-spin gravity

In this paper we construct holographic interface solutions in the Chern-Simons formulation of higher-spin gravity. It is shown that the global regularity of the gauge connection imposes conditions on the conserved currents consistent with interface being totally transmissive or topological. An interface solution connecting the $W_3$ and $W_3^{(2)}$ vacuum is constructed in the $SL(3,R)$ higher spin gravity. An interface solution corresponding to turning on relevant deformations in higher spin $SL(4,R)$ gravity is presented.
