Description
We study holographic theories featuring a non-Hermitian inhomogeneous scalar deformation. We find phases where a purely imaginary current breaks PT-symmetry spontaneously. These PT-broken phases flow in the IR towards a pseudo-Hermitian conformal fixed point realizing PT-symmetry restoration at the end of the RG flow.
