  The paramagnetic phase of the one-dimensional Kondo lattice model is
investigated for electron densities below half-filling using a new mean-field
approach. The physical parameters that govern this phase are identified to be
the spin-flip processes of both the localized and itinerant spins. A
nonmagnetic quantum state, where the local magnetization is a rotating vector
with a nonzero average length, is proposed in order to describe this phase.
This state does not break SU(2) symmetry in agreement with Mermin-Wagner
theorem. The line boundary between this phase and the ferromagnetic phase is
calculated in the coupling-density phase diagram. Also, expressions are
calculated for the velocities of the conduction electrons excitations, and heat
capacity and entropy versus temperature are analyzed. Good agreement with many
of the available numerical data is achieved.
