  We study the effect of disorder in strongly interacting small atomic chains.
Using the Kotliar- Ruckenstein slave-boson approach we diagonalize the
Hamiltonian via scattering matrix theory. We numerically solve the Kondo
transmission and the slave-boson parameters that allow us to calculate the
Kondo temperature. We demonstrate that in the weak disorder regime, disorder in
the energy levels of the dopants induces a non-screened disorder in the Kondo
couplings of the atoms. We show that disorder increases the Kondo temperature
of a perfect chain. We find that this disorder in the couplings comes from a
local distribution of Kondo temperatures along the chain. We propose two
experimental setups where the impact of local Kondo temperatures can be
observed.
