  We study the phase diagram and transport properties of arbitrarily doped
quantum wires functionalized by magnetic adatoms. The appropriate theoretical
model for these systems is a dense one-dimensional Kondo Lattice (KL) which
consists of itinerant electrons interacting with localized quantum magnetic
moments. We discover the novel phase of the locally helical metal where
transport is protected from a destructive influence of material imperfections.
Paradoxically, such a protection emerges without a need of the global helicity,
which is inherent in all previously studied helical systems and requires
breaking the spin-rotation symmetry. We explain the physics of this protection
of the new type, find conditions, under which it emerges, and discuss possible
experimental tests. Our results pave the way to the straightforward realization
of the protected ballistic transport in quantum wires made of various
materials.
